GETTING TO KNOW CHROMIRA
Introduction
Ø Software
This next section is meant to familiarize you with the Chromira Printer’s software system.
This system is comprised of three programs:
Chromira Printer Controls all internal operations of the Chromira machine.

Performs all actual image data processing. Manages the
print job queue, under the user’s direction from Chromira
Workstation.
Chromira Workstation Main user-interface. Functions as “front-end” for submitting

work to the Chromira printer and for monitoring the queue
from anywhere in the network.
Chromira Balance Allows user to calibrate the machine to get optimal color
balance and print quality.
Each of these three programs will be described in more detail. The data flow
between these programs, and the networking issues associated with them, will be
discussed after.
9
THE CHROMIRA SOFTWARE
Chromira Printer
The Chromira Printer program, which controls the mechanical movements and electronic
activity of the machine, runs only on the computer installed in the Chromira itself. It handles
all of the image data processing as well as the print management, maintaining a queue of
jobs to be printed. The user’s control of this queue is executed through the use of Chromira
Workstation, which is detailed later.
Starting it up
When you first start the Chromira Printer program (Chromira Printer.EXE), a start-up self-test
screen will appear and will run through a comprehensive battery of tests. If all is well at the
end, the Chromira Printer’s main screen will appear. If there are any failed self-tests, the self-
test screen will remain, indicating them in red.
Note: If there is no paper loaded in the Chromira, the “Tension Paper Test” will fail. This is
normal. Simply click Finish to close the self-test screen and proceed to the main screen of
the Chromira Printer program.
Chromira 10
The Chromira Printer Main Screen
This is the main operations screen of the Chromira Printer control program. This is the screen that
will be displayed most of the time while the machine is in use or standing by. The various parts of
this display are described here in more detail.
Control Buttons:
Offer convenient access to various important functions and dialog
boxes. (See below.)
Printer Status:
Reports the current status of the Chromira, or if any errors are
present (For example: out-of-paper).
Current Prints:
Displays the jobs that are currently being printed at any given
moment. Multiple prints will show up here if they are being printe
side-by-side (nested prints). “Jobs in Queue” displays the numbe
of prints in the Queue in addition to those currently printing. “Tim
Remaining” displays the time remaining for the current prints only
Emulsion Information:
Displays information about the paper currently loaded in the
Chromira. Indicates the length of paper remaining on the roll
(“Supply”) and the amount printed since the last time paper was
unloaded from the printer for processing.
The Chromira Printer Main Screen
Control Button Descriptions:
Stop Print: This button will immediately pause printing action when clicked. A dialog box
will be displayed, giving you the choice of either continuing the current print or
canceling it.
Online / Offline: Like a standard desktop printer, this button toggles whether or not the
Chromira will continue to print after the current print (if any). This can be thought of as a
“hold-the-queue” button.
Emulsions: This displays the Emulsions Dialog Box, which allows you to select or modify
emulsion files. By keeping Emulsion Files, the Chromira can keep track of different RA-4
materials. This function is described further in following sections.
Preferences: Displays the Preferences Dialog Box, where you can set various aspects of
the Chromira’s behavior.
Test Print: Places a Chromira Test Image into the print queue. This is the Calibration
Image that you will use to calibrate the Chromira for optimal print quality.
Diagnostics: Displays the Chromira’s Diagnostics Dialog Box, which allows you to run an
array of comprehensive Self-Tests and other diagnostics routines.
Next, we will look at the various Dialog Boxes that allow changes to the Chromira’s preference
settings, and at the Emulsion files that allow Chromira to track different types of photo material.
11
The Chromira Printer Dialog Boxes
In this section we take a look at the various dialog boxes available in the Chromira Printer software.
These boxes allow us to modify various settings, such as those pertaining to the type of papers we
use in the Chromira.
The Emulsion Dialog Box
The Emulsion dialog box allows

the user to select the type of photo
material to be used in the printer. The
Chromira can accommodate any
number of different RA-4 type materials.
Each material’s settings are held in an
“Emulsion File” (.EMU extension) on the
Chromira’s hard disk. This dialog box
allows us to make changes to these files,
and copy them for use with new
emulsions.
The various parts of this box are explained

below.
Emulsion File:
The Chromira Printer uses Emulsion Files to keep
track of the different materials that are used in
the printer. These files are saved in the Chromira Printer folder on the computer’s hard disk with a
“.EMU” extension. Each material gets its own Emulsion File, which holds all of the calibration
information for it associated material.
Clicking theBrowse
Browsebutton next to the
Emulsion File readout will prompt you to
select an Emulsion File. From the file
browser window, you can copy an existing
emulsion file to use as a starting calibration (Any blank area
for a new material. in file list)
To copy a file, use the right mouse button to

click and drag an existing EMU file to a blank
part of the file list. Click once (with the left
mouse button) on the new file to re-name it.
Note: be sure to include the “.emu”
extension, or Chromira Printer will not
recognize the new file.
Emulsion Profile:
The Chromira Printer can accommodate color
profiles for precise color management of your printed output. If you use color management, and
have a color profile for the Chromira, you can select the color profile that is to be used with all
prints from this particular emulsion. You can do this by clicking the Browse button next to the
Emulsion Profile readout, and selecting an “.ICM” Color Profile file. When first starting out with the
Chromira, it is not necessary to use color profiles.
Chromira 12
Material Name or Emulsion Comment:
This field is simply a comment area that
can be used to name the material this file represents. This is the “Emulsion” name that appears
in the main screen of the Chromira Printer program. You can type any words here that you
wish, usually a description of the material, and perhaps the emulsion batch number from the
particular roll you are using.
Other Emulsion Information:

These settings are important for the proper
functioning of the Chromira and it’s calibration
system when using a given material. The fields
are as follows:
Width: The width of the physical roll of material, in inches.

Emulsion In/Out: This setting tells the Chromira which way the material is wound on its core. It is
important for the machine to know which direction to turn its cure hubs when tensioning the
paper.
Material Type: Tells the Chromira what type of material the emulsion is: regular Paper,
Transmission Film, Clear, etc. The Chromira’s calibration system uses this information for optimal
performance.
Supply:Indicates
Supply: the amount of paper still remaining on the roll, in feet.
Exposed: The amount of paper that has been exposed. This number can be reset at any time
from the Emulsion dialog box, or the main screen of the program. This number, if it is reset to
zero each time prints are unloaded from the Chromira for processing, will indicate the amount
of paper waiting for processing at any give time.
Material Brand:Tells
Brand: Chromira the name of the roll’s manufacturer.
Color Settings:
Each Emulsion File can store color offset settings to
make different materials print the same color,
given the same image file. These settings are usually
automatically set by the Chromira’s Calibration system, but you can make manual adjustments
as well. The units are in standard CC’s as measured on the print using a densitometer (like the
X-Rite 810, etc.).
The color names indicated on the window tell you how the print will be affected. Change the
color settings by clicking a color’s up/down arrows in each channel. For example, clicking the
up arrow in the Cyan/Red box will increase the cyan in your print.
13
The Preferences Dialog Box
The Preferences dialog box allows you to set various operational settings for the
Chromira. Some of these preferences will be important for the Chromira to fit into your
working environment.
The settings are explained below.
Printer Name:
This field simply allows you to assign a name to this individual Chromira Printer. This is the name
that appears for this printer when selecting among multiple Chromira printers from the Chromira
Workstation program.
Printer Width:
This is the physical width of the Chromira, in inches. This number will generally be either 30 or 50,
depending upon the size of Chromira you have.
Paper Edge Offset:

This is a number that allows you to adjust where the image is printed on the paper. Change this
number if your images are being cut off along the left-hand edge of the paper (image too far to
the left on paper), or if you consistently see a white strip along the left edge (image too far right on
the paper).
The Paper Edge Offset number is in printer pixels, 100 per inch. The Calibration Image that is used
for the Chromira’s calibration has a scale at the left end of the image. This scale can be used to
determine how much to change this number if your prints are not positioned properly on the
page.
Width Scale / Length Scale:

Allows the operator to adjust the width or length of prints if the scaling is not correct.
Air Off Option:

This function turns off the air. The air will automatically shut off after the machine sits idle for a
specified amount of time, as determined by the operator.
Chromira 14
Pause Alarm:
Alarm sounds and pop-up window appears to notify the operator that the printer has paused.
Queue Empty Alarm:

Alarm sounds and pop up-window appears to notify the operator that the printer has an empty
print queue.
Diagnostic Data Logging:

When checked, the printer creates a log of all software functions. This feature should only be
turned on when instructed to by an authorized ZBE technician.
Reset Exposed Footage on Reload:

This function will reset the exposed footage anytime the machine has been reloaded.
Automatic Screen Blank When Door Opened:

With this feature checked, the Chromira monitor will blank to a dark screen when any of the paper
access doors are open.
Automatic Screen Restore When Door Closed:

With this function checked, the Chromira monitor will to restore to its normal function when both of
the paper access doors are closed.
Start Chromira “Online”:

If this function is checked, the printer will automatically start printing anything ready in the print
queue once the Chromira Printer Program is launched and the opening Diagnostics are run.
Audio Prompts:
Allows for audio when checked.
Low Paper Warning:

Warning message will notify the operator when the machine is low on paper.
Automatic Paper-Straightening:
With this function checked, the machine will drive the paper back and forth 2 times with a
distance of 24 inches to allow the paper to straighten itself. After, the paper will be returned to its
original position so no paper is wasted.

Chromira 16
Chromira Workstation
ZBE provides three programs, which are associated with the Chromira. The Chromira Workstation
allows the user to submit and set preferences for each image ready for printing. It acts as the
main “Front-End” for Chromira, letting you setup hotfolders and submit print jobs directly. The
Chromira Workstation may be loaded on to any computer as longs as the computer meets
certain criteria. Any number of copies may run concurrent with the ZBE Chromira. The
Workstation runs anywhere on a Network that has access to BOTH Chromira PC and File Storage
Server Computer.
Initial Setup
To begin, one must first install the workstation program. A CD or Internet download is
available for the operator. Contact ZBE if you are unable to locate a copy of the
program. The computer must meet the following before installing the software.
1- The computer must be PC. If it is a Macintosh, Virtual PC must be loaded

on it before installation of the software. Virtual PC will allow the workstation software
to run on your Macintosh.
2- The computer must have at least a Pentium processor and 64 Megs of RAM.
However, a faster processor along with more RAM will allow the Chromira to print
faster.
3- The computer must have Windows nd 98edition
2 or a more recent version.
4- The computer must interface with the network and must be able to see the
Chromira Computer.
Loading the program on a computer with older operating systems can result in
compatibility issues and certain errors.
Once it has been established that your computer meets the requirements, execute the
Chromira install shield. Select the Chromira Workstation and follow the instructions. After
installation is complete, a Workstation Icon will be displayed on the desktop. Double click
on this Icon and it will launch the Workstation program. Now the operator must establish
the location of the Chromira Printer. Located at the top of the Workstation window is a set
of pull down menus. Locate the “printers” selection and select it. Once open, the Edit
Printer window will appear (See Diagram below). Locate the Browse button and click on it.
You must now browse for the Chromira.PR file. The Chromira.PR file is the Chromira Printer
identification. The PR file is located in the Chromira Printer folder on the root drive (C:) of
the Chromira computer. Once you have located the Chromira.PR file, select it and check
it as active. If you have multiple printers, you must browse for all and then select the one
you want to print to as active. When complete, click the OK button to end the initial set
up. You are now ready to submit prints to the Chromira Printer via this location.
If your lab has multiple Chromiras, and you have set up the workstation to be able to print
to any of the printers, you may also access the quick printer selection. This is located
under the tool bar of the Workstation main screen. Just click the down arrow and select
the printer you wish to use.
17
Main Print Screen
The Main Print Screen is the one displayed after the Workstation software has been launched (See
Diagram).
When the Workstation is displayed, the lower section is devoted to either one of the following three:
1- Print Queue:
Queue Lists all images from any workstation that has been submitted to the
Chromira Printer. It counts for running prints, prints on hold, and prints waiting to be
printed. The Print Queue will allow any number of images to be submitted,
permitting the machine has enough paper length to print all images. If there is an
insufficient amount of paper to print the amount of images submitted to the
queue, the printer will display an error message and two buttons: “Hold/Release
Job” and “Delete Job”.
Hold/Release Job: This button will either place a job on hold or allow a job to go
through, depending on its status prior to clicking on the button. First highlight the
file or files and click on the button.
Delete Job: This button will delete any files that are highlighted.
2- Printer History:
History Lists all images that were printed on the Chromira Printer.
3- Local History:
History Lists all images that were submitted from this workstation.
Checking any one of the three will make activate the selection.
For each of the three, the workstation software will display the following on an information bar
above the queue window:
1- Status: Using the signal light icon will show if the Chromira is printing, on hold, or
done.
2- File Name: Displays the file name of the image that has been submitted.
3- Print Width: Displays the actual width of the final print.
4- Print Height: Displays the actual height of the final print.
5- Quantity: Displays the numbers of images printed.
6- Priority: Displays the priority that was given to an image.
5- Paper Type: Tells the paper type loaded in the printer.
6- Start Time: Displays only with the “Print Queue”. Lists the time a job has started
printing.
7- Finish Time: Displays with both the “Print Queue” and the “Print History”. Displays the
time the Chromira completed printing a file.
8- Submitted:
Submitted Displays only with “Local History”. Displays the time the file was
submitted from the workstation.
9- Operator:
Operator Lists the workstation operator who submitted the image.
Chromira 18
Submit Print
The main function of the workstation is to submit prints to the Chromira Printer. Before
explaining the process of submitting prints, an explanation of Printer functions is necessary.
The Chromira Workstation prints via the network. ZBE designed a system that removes the so-
called “Front End” of the printer, so that files do not need to be loaded to the Chromira
Computer for printing. The Chromira computer is designed to operate the printer and is not
designed to be an images server.
ZBE calls this a “High Efficiency Workflow System”. How does it work? To begin, one should
have a separate computer over the network to be designated as the image server. This
should be a computer with a rather large hard drive and a fast processor. Each workstation
should be allowed access to this computer in order to submit prints to the Chromira Printer.
When submitting an image to the printer, the user locates the file through the workstation
software. Once this is done, the workstation software submits what we call a Tag file to the
Chromira Printer. This Tag file does not have the actual file in it. It holds the file name, location
and print preferences. Once the Chromira Printer receives the tag file, it goes out over the
network and finds the image file to be printed. It then opens up a small portion of the file and
takes that information back to the printer. At the printer, it processes the information and starts
printing. After completion of this task, it starts the whole procedure again, until the full file has
been processed and printed. This system allows the printer to move small bits of information
back and forth, thus creating little network traffic.
Now that you have a general idea of how the system works, you are ready to learn how to
submit a print via the Chromira Workstation. To Submit a print, locate the pull down “File”
menu. There you will find the Submenu “New”. Select it and the Submit print window will pop
up. You may also click on the New icon in the tool bar. Another shortcut is Control + N.
Once the window is open, the operator may choose anything that has to do with the print
preference on this window. Below is an explanation of submit functions.
1- Print File: It is here the operator browses for the image to be

. printed.
2- Print Size: The print size function allows the operator to set the final print size. If
“constrain proportions” is checked, you need only to set either the width or height. If
constrain proportions is unchecked, one must set both width and height.
3- Borders: Allows the operator to set borders around the print. The borders will be the
base color when material is unexposed.
4- Scale: With this function the operator can use the scale % to set the size of the print.
5- Resolution: The number of pixels displayed per unit of printed length in an image,
usually measured in pixels per inch (ppi). An image with a high resolution contains
more, and therefore smaller, pixels than an image of the same printed dimensions
with a low resolution. The Chromira Printer is a 300 ppi printer. Thus any file that is not
300 ppi will need to be resampled up to 300 ppi using an interpolation method.
6- Interpolation: When an image is resampled, Chromira Workstation uses an
interpolation method to assign color values to any new pixels based on the color
values of existing pixels in the image. The more sophisticated the method, the more
quality and detail from the original image is preserved. The Workstation program
allows you to choose from one of the three following methods of interpolation:
a. Bicubic Interpolation: The slowest, but most precise, method,

resulting in the smoothest tonal gradations. Bicubic is set as the
default interpolation method.
b. Bilinear: This interpolation is a medium-quality method.
19
c. Nearest Neighbor: The fastest, but least precise, method. This method
can result in jagged effects, which become apparent
when distorting or scaling an image or performing multiple
manipulations on a selection.
7- Applying ICC Profile: When checked, will apply the ICC Profile. For more information
see the section titled ICC Profile.
8- Constrain Proportions: This function when checked allows the operator to keep the
dimensions of the image without distortion.
9- Resample Image: Resampling refers to changing the pixel dimensions (and therefore
file size) of an image. When you downsample (or decrease the number of pixels),
information is deleted from the image. When you resample up (or increase the
number of pixels), new pixel information is added based on color values of existing
pixels. You specify an approximation or interpolation method to determine how pixels
are added or deleted.
10- Copies: This function allows the operator to set the number of copies to be printed.
11- Rotation: This Function has 5 different selections which are listed below:
a. Do Not Rotate: When selected, will print the image as is.

b. 90 degrees CW: Rotates image 90 degrees Clockwise.
c. 90 degrees CCW: Rotates image 90 degrees Counter Clockwise.
d. 180 Degrees: Rotates the image 180 degrees.
e. Best Fit: This function will rotate image to maximize paper usage
lengthwise.
12- Pause After Print: This function, when checked, will pause the printer after the file has
been printed.
13- Submit Job on Hold: Submits the image file on hold in the Print Queue.
14- Delete File after Printed: Deletes the file after it has been printed.
15- Priority Setting: This function allows the operator to set the print priority. Lower
numbers stand for the highest priority.
16- Nesting: When “Ok to Nest” is selected, the printer will automatically nest the images
across the width of the paper, thus yielding the greatest amount of paper usage.
When “Print Alone” is selected
the printer will print one print across the width of the
paper. This selection leads to a greater amount of paper waste.
17- Crop Marks: There are three selections in this function. The first is “No Crop Marks”. This
function prints with no crop marks around the image. The second selection is “Crop
Marks”. This selection will print crop marks around the image. Each crop mark takes
up a ¼ inch. The last of the selection is “Chromira Trim Marks”. This operates only with
the Chromira Trim. Please see the Chromira Trim manual for direction on its function.
18- Print Data: This Function, when checked, will print a data line with the image. Please
see the section in the Chromira Printer Software on Print data settings.
19- Color: This button opens up the Color Settings. These settings are “On-the-Fly”
changes, meaning any color, contrast, or saturation changes will not effect the core
file. They are only applied when the printer is printing the file. Each value is in CC
units. There are different settings that can be made. They are listed as follows:
a. Cyan/Red: A positive value will add cyan to the print. A negative value
will add red to the print.
b. Magenta/Green: A positive value will add magenta to the print. A
negative value will add green to the print.
c. Yellow/Blue: A positive value will add yellow to the print. A negative
value will add blue to the print.
d. Dark/Light: A positive value will add density to the print. A negative
value will decrease the density of the print.
Chromira 20
e. Contrast/Flat: A positive value will add contrast to the print. A negative value
will decrease the contrast of the print.
f. Saturation/Less: A positive value will add saturation to the print. A negative
value will decrease the saturation of the print.
20- Exit: Clicking on this button will exit the operator from the submit print window.
21- Print: Clicking on this button will submit the print to the Chromira for printing.
Sharpening: The operator has the ability to manipulate the focus of the file by applying this
feature. It allows the user to sharpen the image without changing the structure of the TIFF file.
To use the sharpening feature, the user must adjust the amount of sharpening until the desired
effect is achieved. The “threshold” function determines the amount of pixels it samples in an
area, which in turn adjusts the sharpening. A preview is available to view the amount of
sharpening, which will occur to the image.
Pull Down Menus
Located at the upper left-hand section of the workstation window is a series of pull down
menus. Each one pulls down to a series of sub-menus. Each selection is listed below:
1- File
2- View
3- Settings
4- Printers
5- Hotfolders
6- Help
File: The “File” pull down menu opens up to three submenus. They are listed below:
1- New: This selection allows the operator to open up the Submit window,
which can also be accessed by hitting Control + N on keyboard. See the
section called “Submit Print” for information about submitting prints.
2- Create Default Print: This selection allows the operator to choose default
settings for the submit window.
3- Exit: This selection will terminate the workstation program.
View: The “View” pull down menu opens up to two sub items. These two items are “Tool Bar”
and “Status Bar”. Selecting the tool bar will display quick click selections, which are
locatedbelow the pull down menus. Selecting the status bar will activate the status bar at the
bottom of the window.
Settings: The “Settings” pull down menu opens up to four submenus. They are listed below:
1- Queue Alarm: When checked, the workstation software will

generate an alarm window stating the Print Queue empty.
2- Preferences: When selected, a window will pop up and in this window are
the following items:
a.Default units: Allows the operator to select measurement units

they wish to use.
b. Operator Name: Asks the workstation operator to list his name
in the print queue when the image is submitted.
21
c. Vertical Space Between Prints: The operator can adjust the
space between prints by entering a value here.
d. Lab Name: Gives the workstation operator the ability to list the
lab name with the submission of the print.
3- Long File Names:

Names Allows for long file names.
4- Chromira Trim Marks:
Marks Allows the operator to adjust the Chromira Trim
marks. Please see Chromira Trim manual to set preferences.
Important:
Important:
Must have Chromira Trim to be able to use this function. If you do and
do not have access to this function, please contact ZBE immediately to
obtain the password to enable this function.
Printers: Please see section under initial set up.
Hot Folders: With this function, you can submit multiple files simply by placing them in a folder
that has been designated as a hot folder. To begin, one must create a folder, with the intention
of using it as a hot folder. This folder should be located on a drive with a lot of space. Once this
is done, you will be ready to set up the hot folder using the Chromira Workstation. Select the pull
down menu “Hot Folders”. Select “Edit Hot Folder” function and the Hot Folder window will
appear. The operator should then browse for the designated hot folder.
Once that is completed, click on the “Hot Folder Defaults” button. A window will pop up,
resembling the submit window. It is here that the operator sets up the preferences for the hot
folder. However, a major difference is in the size setting. Since most of all the files will be of
different native sizes, the operator must only set one of the print size dimensions. For example, if
the operator wishes all of the files to be 8 inches wide by whatever length, he then would set the
width dimension to 8 inches and the printer will let the height dimension fall to whatever length
compliments the width. Once all settings have been selected, click the save button and the
window will disappear. In order to make the hot folder active, check “Select Active”.
Help: Allows the operator to access the help log.
ICC PROFILES
An ICC profile is a color space description. The ICC profile format was defined by the
International Color Consortium (ICC) as a cross-application standard. ICC profiles help you
reproduce colors accurately across different platforms, devices, and ICC-compliant
applications.
The Chromira uses an ICC engine to interpret the ICC profiles that describe the RGB color space
you are using in your system. You can select from existing ICC profiles or create your own. These
profiles can then become part of your image files. The engine interprets the ICC profiles to
automatically manage color issues among different color models as well as color issues
between your monitor, other monitors, and the final print image. Although you do not have to
use ICC profiles, it can greatly simplify color management.
There are two types of profiles that will be needed to successfully print for color accuracy. The
first of the profiles is the Input Profile. The input profile is associated with the file to be printed. It
will include color profiles generated by your monitor and or scanner. They typically are
embedded into the file to be printed. However, if they are not, they may be applied when the
file is submitted. The other profile needed is the Output Profile. This profile should be
generated specifically for your lab situation. It is a process of printing a color chart from the
printer and processing. Once done, it will be read on a spectrum analyzer. From there, the
Chromira 22
information is compiled and an output profile is set. In order to perform this task a color
management system is needed. For more information, please contact ZBE.
Installing Profiles in your System
To begin, you will need an output profile. Launch the Chromira Printer program and click on
the emulsion icon. Look through “Select ICC Profiles” and browse for the correct output profile
for that emulsion. Once you have browsed for it, the profile will live with that EMU file. To
remove, just browse for a new one.
Next, launch the workstation program. Click New to open the submit window. Locate the
section that applies the profile.
Check the box if the file to be printed has the input profile embedded in it. If it does not, click
on the “Select Profile” button.
The following window will appear:
It is here that you must browse for the input profile. Once done, click OK.
You may also override any existing profile. Click the box that applies and browse for the
profile. This allows one to quickly change profiles without removing the existing ones.
For Rendering Intent, select the profile that applies to your Color Management system.
ZBE has provided the tools for the application of a color management system. However, we
(ZBE) are not Color Management experts. We will provide as much support as we are
capable. However, it may be necessary for you to consult a color management expert to set
up a system.

Chromira Balance
The last program provided with the Chromira is the Balance Program. This program is very
important for balancing the printer for your lab.
Initial Set Up
In order to balance the printer, the operator must first give the location of the printer to the
balance program. This procedure is similar to that of the workstation browsing for the printer.
Click on the browse button located at the top of the window:
Find the Chromira.PR file and select it. Once this is done, verify that it has been accepted
by looking at the emulsion and material type. The current emulsion and material type
should be displayed.
Setting up the Densitometer
The Chromira software will allow the user to interface with certain densitometers. Please see
appendix for models and series of densitometers that are compatible with the Chromira.
Also listed are the settings for each one. Follow the procedure, which applies, to your
densitometer. Click on the “Setting” button to access the setting for the Chromira.
Balancing the Chromira Printer
Overview
The ZBE Chromira Printer provides the user with the means to calibrate the printer for use with
nearly any RA-4 type of photographic material. This "self-calibration" allows your lab to
maintain the Printer through an in-house procedure, without the aid, and associated delays
and expense, of an outside technician.
This calibration is provided by the Chromira Balance Program. Chromira Balance allows the
computer to "look" at a Test Print and make changes to the Emulsion (*.EMU) File associated
with the photo material being calibrated.
This Calibration process involves running a series of Calibration Cycles. Each calibration
cycle is comprised of the following steps:
1- Make a test print

2- Visually look at the Test Print and determine which analysis is required.
3- Run the required analysis on the test print (Scanner and /or Densitometer).
4- Apply the changes to the .EMU file associated with the material being calibrated.
These four steps are repeated until the quality of the print is good enough for production
work. The details of each step are now described.
Chromira 24
The balance procedure is comprised of two parts:
Scan Balance: The scan balance provides the user the ability to correct for scan
lines which printers of this sort can produce.
Densitometer Balance: The densitometer balance controls the color balance of the
printer.
Both of these balance procedures will be covered in detail in this section.
Procedure
Start by deciding where the balance application should be installed. The Balance application
does not need to be on the Chromira computer. It can be on any other computer as long as
the computer meets the following requirements:
a. Computer is a PC, preferably Windows (any version, example, 95’ 98’) or Windows NT.
b. Computer is logged and shared on network so that it can communicate with the
Chromira computer.
c. Computer has a scuzzy card to allow for the UMAX scanner.
d. Computer has a free com port for densitometer (optional).
If you do decide to install the balance application on another computer other than the
Chromira printer, please see installation technician or call ZBE technical support.
Making a Calibration Image or Test Print
Once the Balance Application location has been established, the next step is to start the
calibration procedure. A calibration image will be needed for the balancing. The location of
this image can be found on the Chromira Printer Application. Clicking on the calibration icon
on the icon bar of the Printer application will automatically print the image.
25
Calibration Image: The Calibration image is used for the balancing procedure of the
printer. To create the image, simply click on this icon and the Chromira will
automatically size the image to the paper and print it on the paper already loaded
on the machine.
Before you start the Test Print, it is important that you select and setup the proper Emulsion file for
the photographic material you intend to calibrate. This can be done from the Emulsion dialog
box in the Chromira Printer program.
These Test Prints are placed in the print queue just like all other Chromira print jobs; they will show
up in the Chromira Workstation program's queue view. The Test Print is simply a job that prints the
"Test Image.TIF" file located in the "C:\Chromira Printer" folder on the Chromira's computer. This Test
Print job is setup automatically by the Chromira Printer program - it is recommended that you do
not change any of the job settings (using Chromira Workstation).
Judging the Test Print
When you retrieve the Test Print from the processor, you will need to determine whether it needs to
be run through the Scanner Analysis or the Densitometer Analysis. This decision is usually quite
simple:
> Test Print is not the correct color: Run

a Densitometer

There are other things to consider, in some cases. If the print is both off-color, and it has lines in it,
then you will need to run both types of analysis. Following are a few rules that will guide you
through this process:
> The color balance of the Test Print is very wrong: The grey looks entirely like some other color.
-- Even if the Test Print has lines in it, run only the Densitometer Analysis this time, then make your
next Test Print.
> The Test Print's color is moderately or slightly wrong: The grey scale has a tint of another color, or
some of the patches look a little off-color AND the Test Print has lines in it.
-- Run both the Scanner Analysis and the Densitometer Analysis. Run the Scanner Analysis first, then
read it on the Densitometer. After both analyses are complete, make your next Test Print.
> The Test Print has lines in it, but the color looks correct
-- Run only a Scanner Analysis. Then make your next test image.
Chromira 26
> The Test Print's color is wrong, but it has no lines in it.
-- Run only the Densitometer Analysis, then make your next test print. If the color correction was
large (the color was very wrong), the Densitometer Balance effects may cause lines in the next
test image, so another Balance cycle will probably be needed.
In summary, Densitometer balance changes (made by running the Densitometer Analysis) can
introduce lines into the next print. The Scanner Analysis will not affect the color of the print, unless
the lines in the print are very severe.
Performing a Scanner Analysis
The Scanner Analysis is intended to remove any lines that appear in the Test Print. To perform a
Scanner Analysis, you will need to use a computer with both a working UMAX PowerLook II or
PowerLook III model scanner hooked up to it, and the Chromira Balance Program. The
computer you use does not necessarily have to be the one in the Chromira.
1: Cut out the Test Print by cutting out the center section of the image, which is surrounded by a
thick black border. Be very careful to cut outside the black border along the sides (vertical cuts).
Your cut across the top of the image is the most important, and must be very straight. To trim
the top of the Test Print, cut between the two thick lines that are located above the thick black
border of the top portion of the image.
2: Place the Test Print on the scanner so that the top of the Print is toward you as you stand in
front of the scanner. The print must also be centered left to right on the scanner. To aid in this,
you can make small cuts at the tops of the two thin vertical lines that are just outside the thick
black border. You can also use your fingernail to make dimples in the paper at these points.
Then, when placing the paper on the scanner, you can align your cuts or marks with the "A4"
arrows on the scanner. Once in position, carefully close the scanner's lid.
3: Click the "Scan" button in the Chromira Balance Program. The Balance program will perform
a couple of automatic scans, and then analyze the scanned image. The balance changes
that the program calculates will not be saved to the EMU file yet.
4: Click the Apply Changes button. This will put the changes that the Balance program
calculates into the Emulsion (EMU) file. A backup of the EMU file (before these changes are
applied) is also made on the Chromira's computer.
If you intend to run a Densitometer Analysis after this Scanner Analysis, you can skip straight to the
Densitometer Analysis, then Apply Changes at the end of both Analyses.
Performing a Densitometer Analysis
The Densitometer Analysis is used to correct the color of the Test Image, and to get all of the
steps in the Grey Scale at proper grey intervals, providing the best tonal range for the
photographic material being calibrated. To perform a Densitometer Analysis, you will need a
densitometer and a computer running the Balance program.
It is highly recommended that you connect the densitometer to the computer through its RS-232
serial port. This will save having to type in the 17 RGB readings that are taken in this procedure.
For this connection to work, you will need to select the COM port number and the baud rate for
your densitometer hookup from the "Settings" button in the balance program.
1: To begin, click the "Densitometer" button on the Balance Program's main window. This
will display the Densitometer dialog box as well as a graph of the target densities for
27
the range of patches from Black (Patch 0) to White (Patch 16). The program is now ready to
accept readings, starting with the black patch zero (0).
2: Read the 17 patches at the bottom area of the test image. Start with the black Patch Zero (0).
After each reading, the "Patch" number in the dialog box will increment one count and the
reading windows for R, G, and B will still look blank. If you do not have the RS-232 port connection,
you will have to type in the RGB readings into spaces provided, then click the up arrow next to the
"Patch" value. You can always review your readings by using the up/down arrows next to the
"Patch" value. The graph view will also change to reflect your readings.
3: Review your D-max targets if this is the first Densitometer Analysis for this
In general,
material.
for
paper materials (matte, gloss, etc.) and for "flex" materials ("ultra-gloss", polyester based), the D-
max targets should be about 2.10 for all three colors. For dura-trans or clear materials (transparent
or translucent films), the D-Max targets should be set to about 2.90 to 3.00 to start with. Please see
the section "D-max Failure" near at the end of this document, or contact ZBE, for more
information.
4: Click the "Done" button. When the last patch, white patch 16, is read, the graph should look
complete. If everything looks correct, the “Done” button will exit this dialog box back to the main
screen, and calculate the changes to the EMU file that are necessary to correct the color
balance. These changes will not be made to the EMU file itself until you click the "Apply Changes"
button.
Remember to click the "Apply Changes" button when you have finished your analyses for this
balance cycle.
Advance Settings
Located in the lower left hand corner of the Balance window is a button marked “Advanced”. To
access it, click on the button. The following window will appear:
Balance Gains:
Refers to the amount of correction the scanner will make with each cycle. The default setting is
set to one for each of the three colors. These values should not be changed, unless directed by a
ZBE technician.
Curve Gamma:
The Curve gamma determines the slop of the contrast curve. The default setting is set to 1.8.
Once again, this value should not be changed unless directed by a ZBE technician.
Chromira 28
Calibration Pitfalls
As with any procedure, with the Calibration process of the Chromira, things can go wrong. There
are two things that can happen during the process of calibrating your Chromira Printer:
D-max Failure
This is where you have exceeded the maximum exposure level that the material you are
calibrating can handle. This is caused by the D-max Targets being set too high in the Chromira
Balance program’s Densitometer window.
Lines That Don’t go Away

This is a situation where, no matter how many Scanner Analysis cycles you have run, there are still
visible lines in your prints. This can be caused by several different things, including D-max failure,
a network settings problem in Windows, or a mechanical problem with the Chromira printer itself.
These two pitfalls of the Chromira Balance process are described here in more detail.
D-Max Failure
Digital photo writers of any type (laser- or LED- based) typically are not able to achieve quite as
high a d-max as that achieved by conventional darkroom (enlarger) printing. Of course, this
depends upon the photographic material being used, and the quality of the chemical process
used to process your photographic prints. It is strongly recommended that you use a “digital”
photo paper if possible.
For any photographic material, there is a level of exposure above which the image on that
material will not get any darker, even if the exposure is increased. This maximum darkness is the
D-max for that material.
The condition known as D-Max Failure can happen when you have set a D-max target in the
Chromira Balance program’s Densitometer window that is too high for the Chromira to achieve
on the particular material being used.
This causes the Balance program to increase the Chromira’s exposure output above the point
where changes in the exposure output will make the desired change in the printed image
density. When this happens, the Balance program no longer has “control” over the image
quality at densities above this level.
This causes the two primary symptoms of D-Max Failure:
1. There are lines in the black (patch zero) that do not go away, even though the rest of
the grey scale has a good balance (no lines).
2. The top two patches in the grey scale (patch 0 and patch 1) look very close to
each other in density.
Keep in mind that these symptoms can, and usually do, happen in only one or two of the three
primary colors. You can look at the shorter color scales below the main grey gradient in the Test
Print, and see if either of these symptoms is happening in an individual color.
If this problem is caused by having set the D-Max targets too high in the Balance program, then
the solution is to find the best D-Max targets that will work with your material.
29
To find the proper D-Max targets for your material, do the following:
1. In the Chromira Printer program, go into the Emulsion dialog box. At the bottom of this
window, locate the color balance settings for the Emulsion. These are the Cyan,
Magenta, Yellow, and Density values.
2. Add 200 to the Density value, and enter this new number here. This will drive the
printed image into the D-Max failure zone, which is what we are looking to do for this
test.
3. Close the Emulsion dialog box, and run a Test Print in the normal manner. Process the
print when the Chromira finishes it.
4. Looking at the resulting Print, you should see that at least the top few patches look like
they are all black. If they do not, then increase the Density setting in the Emulsion
dialog box even more, and try another print.
5. On this D-Max Failed Test Print, take a densitometer reading of the darkest black,
which should be at Patch Zero (0). Write down the reading’s three values (R, G, B).
6. Subtract 7 to 10 points from each of the values that were read in the previous step.
Write down these values. These will be the D-Max Targets to be used in the Chromira
Balance Program’s Densitometer window.
7. Important: Go back into the Emulsion dialog box in Chromira Printer, and set the
Density setting back to it’s original value, after you get a well-blown print.
8. Run a couple of Balance cycles, where you only do the Densitometer analysis. Do not
scan the image during these cycles.
9. After two or three more prints, the Test Print’s grey scale should have all its patches at
nicely spaced density intervals. Once this is achieved, you can run Scanner analysis
cycles to get rid of any lines that have gotten into the balance.
Lines That Do Not Go Away
When performing Scanner analysis balance cycles, you should expect to see some reduction in
the lines in the Test Print with each passing cycle. However, if you do not see improvement after a
few cycles, then there is likely another problem. The lines that do not go away are caused by
something the Scanner Analysis process cannot take care of.
The causes for this type of balance failure are:
1. D-Max Failure: You have exceeded the maximum exposure for this material, above
which changes in the Chromira’s output do not make corresponding changes in the
Print.
2. Networking Problem: The Windows network is set up in such a way that the computer
running Chromira Balance can not open and change the Emulsion (EMU) file on the
Chromira Computer. Note that this can happen even if the Balance program is
running on the actual Chromira Printer’s computer. This problem arises from incorrect
settings in the Windows Networking file access permissions.
3. Mechanical problem: One of several things has gone out of alignment in the
Chromira’s mechanical setup. This should never happen after the machine is
installed, but the mechanical causes are listed here as an aid to technicians.
If D-Max Failure is suspected, please see the previous section regarding how to identify and fix that
condition.
If D-Max Failure is not the cause for your Test Print lines not going away, verify that your network
settings are correct. This can be a cause even if the Balance program is running on the Chromira
Printer computer. When you click the “Apply Changes” button in Chromira Balance, you should
see two messages in the text window of that program that say that the Emulsion
Chromira 30
(EMU) file “has been backed up”, and that it “has been copied back to printer.” If you do not
see these messages each time you complete a balance cycle (“Apply Changes”), or see
some other error message concerning the Emulsion file, there is likely a sharing or permissions
problem in your network settings.
If you determine that these messages are not being issued by the Balance program, go into the
“My Computer” icon on the Chromira computer, and right-click the Drive “C:”. In the resulting
menu, select Sharing. In the share readout, you should see a share name “C”. If this is not the
case, click the “Add Share” button and make a new share called “C”, and give it “Full Control”
access to “Everyone”. You can double-check that the network settings are correct by using
Network Neighborhood to browse to the C: drive on the Chromira Computer. Using “Network
Neighborhood” instead of “My Computer” forces Windows to use the networking system to
access the drive. If this was not the problem, you may have to ask a network administrator to
help find this problem.
If the network settings were not preventing the Chromira Balance program to make changes to
the EMU file, and the lines still do not go away, the problem may be a mechanical
misalignment of the Chromira machine itself.
To check for this, run a batch of images that have even-colored backgrounds extending across
the entire width of the printer. The batch should be about 5 or 6 feet in length and can be a
series of smaller prints, or one large image; the important thing is that the image covers the
entire width of the paper.
When this series of prints is out of the processor, view it so that you are looking at the lowest
image right-side up. This will be the image that was printed first in the printer. Very carefully,
examine the lines in the prints, to see if they happen: 1.) only on one side or the other, 2.) are all
the way across the print, 3.) are across the print, but don’t happen all the time, 4.)go away after
awhile, or 5.) come in after awhile. These lines usually appear as sharp white lines in your

TECHNICAL DOCUMENTS
Simple Windows NT Networking Setup
This document outlines the setup of a simple Windows NT network. For this purpose, we
assume that the “network” consists of only Windows NT Workstation, or Windows 95/98
Machines.
Warning: This network setup will not have security restrictions in place when finished.
For further information and troubleshooting, please see www.microsoft.com. (Their website
is surprisingly helpful!). ZBE assumes no responsibility for problems arising from network
setup issues. This includes any consequences arising from lack of security setup.
We will set up the simplest form of Windows network, using the TCP/IP protocol and
manually assigning each computer it’s unique IP Address. This procedure assumes that
each computer has a functional network card. You should also have your Windows NT
Installation Disk handy (if doing this procedure on a Chromira NT computer, this disk will not
be needed).
Please perform the following steps on each NT workstation:
1. Right-Click the Network Neighborhood icon and select Properties.

2. The Network Properties box will be displayed, showing the computer’s Name and
Workgroup.
3. Click Change, and give your computer the name you want it to appear under in
Network Neighborhood. Click OK.
4. Click Change again. Choose a name for your Workgroup. Most people use their
company name for this. The workgroup will be the same for all computers on this
network.
5. From the Network Properties box, click the tab near the top that reads Adapters so
that we can check that your network interface card (NIC) is present and
accounted for.
6. In the list that will appear, you should see your network card listed. If it is not listed
here, you will need to install a card in your computer along with its specific drivers,
then add the new card in Network properties after rebooting. If your cards
appears ok here, proceed to the next step.
7. Click the Protocol tab. In the list that appears here, you may see a listing for
“TCP/IP Protocol”. If it is here, proceed to the next step. If not, click Add, then
select “TCP/IP Protocol” from the Select Network Protocol box.
8. Double-click the “TCP/IP Protocol” listing in the list of protocols. This will bring up the
“Microsoft TCP/IP Properties” dialog box.
9. The IP Address tab should be showing (if not, click it). Verify that the Adapter shown
is the one installed in this system, looked at in step #6.
10. Click the “Specify an IP address” dot.
11. Fill in the IP Address as “192.168.0.nnn”, replacing the “nnn” (the last set of
numbers) with a number from 1 to 253 which will be unique to this computer. Use
the period (dot) key to advance through the four numbers.
12. Fill in the Subnet Mask as “255.255.255.0”.
13. Make sure the Default Gateway is blank.
35
14. Click the DNS tab. This page should have all blank settings. If there are any entries under the “
Service Search Order” list, delete them. Do likewise for the “Domain Suffix Search Order” list.
15. Click the WINS Address tab. The Adapter should show your network card, but all other fields
should be blank. Also, both check marks should be off.
16. Click the Routing tab. Make sure the “Enable IP Forwarding” check box is blank.
17. Click OK in the “Microsoft TCP/IP Properties” dialog box.
18. Click the Services tab. In the list that will appear, verify that “Simple TCP/IP Services”, “Server”
“Workstation”, and “Computer Browser” are listed. If they are not, you can add them by
clicking Add, and selecting them from the resulting list.
19. Click OK in the “Network” dialog box.
20. This will return you to the Windows desktop, and the computer will ask you to reboot.
21. After re-booting, verify that you can “see” the other computers on the network. Windows
takes up to about 3 minutes for the other computers in the Workgroup to appear. Network
Neighborhood will appear blank until then.
Simple Troubleshooting
> If no computers appear in the Network Neighborhood, and you know you have more than one setup
according to the procedure outlined here, try “pinging” one, as follows:
• Start a Command Prompt (Start Menu, Programs, Command Prompt)

• At the command line, type “PING 192.168.0.nnn” replacing the “nnn” with a number from
one of the other computers on your network.
• The program should respond with “Reply from…” and the IP Address you typed in.
• If you get “Request Timed Out” then the network wiring between the computers, or the hub,
is not functional.
• If this works, the hardware (cabling, hub, network cards) is ok on both computers. This will
mean that the problem is in the Network setup.
• If “ping” worked, try the Start menu, then Find, then Computer. Enter the name of the other
computer. Click Find Now. This should find the other computer (if you got the name right!)
even if it is in another Workgroup.
• If Find does not work, please review the settings you made during the setup procedure.
• If Find works, then you simply have to wait a bit for Windows to figure out the network.
• Also check that you have at least one drive shared on each computer for them to show up
on the network.
• Be sure that you are logged on as “Administrator” on each machine you setup.

Replacing Chromira Linear Encoder Strip
This document outlines the replacement of the Chromira’s Linear Encoder Strip. This Encoder Strip,
mounted to the air-rail of the machine, passes through a Linear Encoder in the head carriage, and
allows the computer to place the pixels onto the photo paper as the head traverses the length of the
air-rail.
Important: The Linear Encoder Strip is very fragile, and should be handled with care. Never fold or bend
it in any way.
The Linear Encoder Strip is held at each end by a clamp attached to the inner surface of the air-rail.
Each clamp uses two screws (markedA andA BB in the drawing below) to secure the end of the Encoder
Strip.
These drawings show views as

seen standing at Take-Up Side of
machine.

Encoder Strip Attachment Encoder Strip Attachment
at Left End of Air-rail. at Right End of Air-rail.
Removing the Old Encoder Strip
1. Loosen the two screws holding the left-end of the Encoder Strip, indicated as
“A” in the above drawing (2 total screws).
2. With the Air-Pressure turned ON, move the head over to your left.
3. Loosen and remove the two screws (“B”) holding the right end of the Encoder Strip. This will free
both the retainer block and the end of the Strip.
4. Remove the Encoder Strip by carefully sliding it to the right. You may have to bend the free end
toward you slightly to get the other end to clear, but keep it level. Move the head further to the
left if necessary to get the old Strip out.
5. Once the old Encoder Strip is free, note which end was the right end and which was at the left.
Also note that the thin film part of the Strip hangs at the bottom.
Chromira 38
Installing the New Encoder Strip
1. Orient the new Strip in the same position as the old one. The thin film part of the
strip should be at the bottom.
2. Gently move the head as far as it will go to the left.
3. Holding the new Encoder Strip level, bring the left end in between the head carriage and
the air-rail. Insert the end into the narrow slot in the Linear Encoder located behind the head
plate. This slot is hard to see; use a small flashlight for a better view. The Drawing below
depicts this slot and the surrounding area.

4. Once the Strip is inserted through the Linear Encoder body, slide the head to the right a little,
keeping the strip in place (slide the strip through the Encoder body at the same time), to
gain access to the screws that hold the left end of the strip in place.
5. Insert the left end of the strip into the clamp that held the old one. The end of the Strip
should protrude from underneath the far side of the clamp by about 1/8 - 3/8 inch (3-9mm).
Once in position, tighten the two screws moderately to hold the end in place.
6. Slide the head nearly all the way to the right, but leave the right end clamp in sight.
7. The right end of the Strip should now be sitting near the proper location at the right end
clamp.
8. Replace the clamp cover and the two screws that hold it in place (removed in Step #3).
Some of the strip will be sticking out from the far side of this clamp. This is normal.
9. Tighten these two screws moderately to hold this end in place.
10. With the Linear Encoder Strip temporarily held in place, you can now align it.
11. At the left end of the Strip, tighten the two tensioning screws about two (2) turns each. These
screws are marked “C” in the drawing on the preceding page. This will make the encoder
strip taut between the two clamps.
12. With the head near the right end of the rail, look at the Encoder Strip’s position in the
Encoder Body slot. It should be centered top to bottom. If it is not, loosen the screws on
39
the right end clamp, and grasp the end of the strip that protrudes from the far side of the
clamp (with your fingers or a pair of needle-nose pliers). While holding the strip tight,
position it up or down as needed, and tighten the screws with your other hand. Double
check that the strip’s position in the slot is centered top to bottom, and tighten the screws
very tight to hold the strip in final position.
13. Move the head to the left, leaving access to the left end clamp.
14. With the head near the left end of the rail, look at the Encoder Strip’s position in the
Encoder Body slot. Center the strip as in the last step. Since the end of the Strip that
protrudes from the far side of the clamp is short, needle-nose pliers may be needed to
hold it for positioning. Tighten the screws very tight once the Strip is in final position.
15. Tighten the Strip Tensioning Screws to make the strip taut between its clamps.
16. Move the head back and forth, using a flashlight to view the strip’s passage through the
Encoder Body. Check that the strip does not make contact with the Encoder body in any
way. If it looks good at each end, but rubs somewhere in the middle, the tensioning
screws can be used to correct this. If the top of the strip rubs against the top of the slot,
tighten the bottom tensioning screw. If the strip rubs at the bottom, tighten the top screw.
Tilt in the strip can also be corrected using the tensioning screws.
17. Adjust the tensioning screws until the strip is straight. As a rule during adjustment, do not
loosen these screws, as a loose screw will not hold a setting. Over-tightening a screw may
cause the left end clamp to slip on the end of the strip, but this can be corrected by
tightening the other one.
If you run out of thread on either of these screws, you can loosen the clamp. Loosen the
tensioning screws all the way and then, re-tighten the clamp.
18. If you need to adjust the left end of the strip in the other axis (side to side in the slot), use
the screws on the other side of the air-rail, which hold the Tensioning Screw Block in place.
There are four screws here: the outer two pull the block toward the rail; the inner two (which
may be set-screws) are threaded in the rail, and push the block away from the rail. If
adjustments are made here, make sure all four of these screws are tight when finished (if
you loosen an outer screw, tighten the inner screw closest to it).
19. As a final check for Encoder Strip rubbing, gently place a finger on one end of the
Encoder Strip, and move the head through its range of motion. Any contact between the
Linear Encoder Body on the head, and the strip, will be felt through your fingertip as
vibration in the strip.

Chromira Scaling Factor Directions
Please follow this procedure exactly as stated:
1. Print the 100inV.tif file that was sent with the software.
2. When you are submitting this file to be printed, the resample button in Chromira
Workstation should be unchecked.
3. The file has lines every 10 inches. It also has a line every inch for the first and the last 10
inches. After the file has been printed, you should take a tape measure and measure the
entire file. You can use this measurement to set the scaling for your Chromira Printer.
4. For example:
Say that you measured the file and it came to 99.25 inches. You would then divide 100
inches by this 99.25 inches. (You divide into 100 inches because this is the actual size of
the digital file.)
100 / 99.25 = 1.00756 (5 decimal points is fine)
5. Next, insert 1.00756 into the Chromira Printer application. After starting the Chromira Printer
application, go to the Preferences screen. To get there, press the button with the “i” on it.
You would then enter 1.00756 into the Length Scale box.
6. That is all it takes to successfully set the scaling for your Chromira Printer. To make sure that
this scaling factor gets applied to each of your prints, you must check the resample
button in Chromira Workstation when you submit a print. The scaling factors only get
applied if this resample button is checked. It would be best to default the resample
button as checked.

Appendix A (refer back to page 44) shows the view from the top of the machine. There
are six (6) screws that mount the junction board, and they are located from the top.
Please label each AMP connector so they are all plugged in at the proper position.
Appendix C (refer back to page 46) is the view from the bottom of the machine. It is
very important to connect all the cables in the right positions. The best thing to do is

Amp Connectors: These are the cone-shaped connectors that have wire bundles
connected to them.
Note: Before starting the procedure, please power down the computer and unplug the
main power plug of the machine.
Junction board replacement procedure:
1. Unplug main power and air value AMP connectors (See Appendix C).
2. Remove all AMP connectors from the top of the machine. (Please note positioning.)
Unscrew the plastic ring at the base and the connector will pull out.
3. Remove amplifier cables. (It’s very important to note positioning Dohere)

unscrew each lead. Each cable is screwed in to a connector. The connector itself
will pull out of the slot in which it is housed on the PCB board.
4. Remove motor control signal cable (See Appendix C). It is very important to note
the orientation. The connector will have a white mark on one side. That mark
locates pin one. You must be sure to plug it back in with the white mark on the
same side as the “1”, as indicated on the junction board.
5. Remove both the motion control main connector and the motion control auxiliary
connector. (See Appendix C for position.)
6. Unscrew each of the six screws that mount the board to the main deck. The screws
are located on the top side of the deck (See Appendix A)
7. Remove board and replace with new one.
8. Screw each of the six screws back into place.
9. Replace all AMP connectors on the top side of the deck. (Please note positioning.)
10. Replace all amplifier connectors on the bottom side of the deck. (Again, please
note positioning.)
11. Replace motor control signal cable. It is very important to note the orientation. The
connector will have a white mark on one side. That mark locates pin one. You must
be sure to plug it back in with the white mark on the same side as the “1”, as
indicated on the junction board.
12. Inspect motion control main and auxiliary cables for bent pins or overall damage.
13. If cables are fine, place them back in to position.
14. Replace all other AMP connectors on the bottom side of the deck.
15. Double check to see if all cables is properly seated.
16. Plug Chromira back in and power up the computer.
This completes the replacement procedure.

16. Remove top cover on motion control power supply
17. Mount the new Motion Control Power Supply to deck in
the same position as the old one, using the four
screws removed in step #8. Air Solenoid Assembly
18. Put the new Power Supply’s cover back on.
19. Route the two cables from the new Power Supply to the Junction Board (female
connector goes towards the feed side and male connector goes towards take up
side.)
20. Plug the wire from the Air-Solenoid, into the receptacle in the new Power Supply.
21. Locate the air solenoid switch on the power supply and set it to the off position.
22. Connect the new Power Supply’s AC power cord to the top-most plug in the
Chromira’s power strip. Place the cable in the trough provided for it (where the old
one was).
53
Note: All switches and manual shut-off knobs should be in the off position. When in this position, it
will allow the computer to have control of the air. If a switch or knob is on, the air will stay on and
the printer will fail the air solenoid test.
« This completes the installation of the Chromira Air-Solenoid and the new Motion Control Power
Supply. When the machine has started up again, go into the Preferences Menu in Chromira
Printer, to set the amount of time the air will stay on after the machine is idle (time range 1 to 60
minutes).

GENERAL ALIGNMENT PROCEDURE FOR CHROMIRA
PAPER-TRACKING
This section describes the procedure for bringing a Chromira printer into alignment for proper
paper tracking. This does not include optical alignment (viewer) or chassis setup (initial
assembly). This document assumes that you know how to do the standard Core-Shaft Parallel
Adjustment Procedure, and how to adjust the Drum parallel position, using the Main Bearing
Tube (Donkey-Dick) push-pull mounting screws.
Start with a machine whose chassis is completely assembled, with dancer arms installed. The

onto the chassis.
A: FEED-SIDE CORE SHAFT ALIGNMENT and DANCER ROLLER LEVEL
1. Start at the Feed Side of the Machine. Remove both core hubs from their shafts. Install
and setup the Thou-Indicator for aligning the core-hub shafts.
2. Put the Feed Dancer in the “in” position. Place a test support between the Dancer Roller
and the main tie-tube of the machine to hold the arm roughly in the paper-loaded
position. Be sure that this support is at the midpoint of the Dancer’s Roller (this will be off-
center of the drum). Use only one support located at the midpoint of the roller (not two on
each end).
3. Measure and align the core drive shafts in the normal manner.
4. Once the shafts are in true parallel to the rail, change the indicator position to read the
top-dead-center area of the Dancer Roller (Dancer Roller Vertical Parallel check). This is
done by poking the indicator’s little feeler between the Dancer’s Tie-Tube and the Roller
itself, resting upon the top of the Roller. Leave the Dancer Arm supported by the single
support placed midway along the Dancer Roller.
5. Indicate along the length of the Dancer Roller. You should see about 15-20 thou of rise in
the middle – this is normal. Take your measurements to indicate the difference in height
at 1 inch in from each end of the roller.
6. Check that the Dancer Arm Roller Leveling Screw is installed on the side-plate of this
Dancer Arm, and that the belleville washers are firmly compressed between the side plate
lever, and the jam-nut installed on the screw. These washers should be fully compressed
by the nut, and this screw should only turn with difficulty.
7. Adjust the Dancer Arm Roller Leveling Screw, and repeat the sweep at 1 inch from each
end, until both ends read the same height. Remember that the middle will indicate a rise
due to the pressure from the single support holding the Arm in position. Just worry about
the ends – they need to be at the same reading.
B: DRUM PARALLEL ADJUSTMENT (Horizontal Plane)
1. Place the Feed-Side Dancer Arm in the “out” position.

2. Leaving the Thou Indicator in place on the Feed-Side of the machine, reposition it to
indicate the side-dead-center of the Chromira’s Main Drum for measuring the skew (in the
horizontal plane) of the Drum.
3. Indicate along the length of the Drum, and adjust the Drum’s parallel in the horizontal
plane to bring it into line if it is outside the normal tolerance for this adjustment.
55
C: TAKE-UP SIDE CORE-SHAFT ALIGNMENT
1. Move and install the Thou Indicator on the Take-Up Side of the machine. (The rest of this
section is the same as the procedure done on the Feed-Side of the machine.)
2. Remove both core hubs from their shafts. Install and setup the Thou-Indicator for aligning the
core-hub shafts.
3. Put the Take-Up Dancer in the “in” position. Place a test support between the Dancer Roller
and the Main Tie-Tube of the machine to hold the arm roughly in the paper-loaded position.
Be sure that this support is at the midpoint of the Dancer’s Roller (this will be off-center of the
drum). Use only one support located at the midpoint of the roller (not two on each end).
4. Measure and align the core drive shafts in the normal manner.
5. Once the shafts are in true parallel to the rail, change the indicator position to read the top-
dead-center of the Dancer Roller. This is done by poking the indicator’s little feeler between
the Dancer’s Tie-Tube and the Roller itself, resting upon the top of the Roller. Leave the Dancer
Arm supported by the single support placed midway along the Dancer Roller.
6. Indicate along the length of the Dancer Roller. You should see about 15-20 thou of rise in the
middle – this is normal. Take your measurements to indicate the difference in height at 1 inch
in from each end of the roller.
D: DRUM PARALLEL ADJUSTMENT (Vertical Plane)
1. Load paper onto the Chromira. Make sure that the roll that is used has a perfect wind, and is
not poorly aligned on its core.
2. Set up the Tenths Indicator to read the vertical position of the Drum in relation to the head
(Main Drum Vertical Parallel Adjustment).
3. Perform the standard Main Drum Vertical Parallel Adjustment procedure.
4. Remove the Tenths Indicator.
E: FEED-SIDE DANCER ROLLER FINAL PARALLEL CHECK
1. On the Feed-Side of the machine, set up the Thou Indicator for measuring the Dancer Roller
Vertical Parallel, as in step 4 of section A. Advance the paper a few inches (using the paper
advance button) before taking readings in the following steps.
2. Indicate the deviation of the top-dead-center of the Dancer Roller. It should be very close
(<.003”) to parallel. The rise due to paper tension at or near the midpoint of the roller will be
about .005 to .010 inch. This is normal. Check that both ends are still at the same reading
(level with each other). If they are not, try advancing the paper a little more (a few more
inches), and take the readings again. If the ends are still not even (within .003), make the
necessary adjustments to the Dancer Arm Roller Leveling Screw, advancing the paper a little
after each adjustment. Technically, no adjustments should be necessary here.
3. Change the position of the Thou Indicator to read the side-dead-center of the Dancer Roller.
4. Check that the deviation here (Dancer Roller Horizontal Parallel) is no more than .007 inch.
Note: There is no adjustment for the Dancer Roller Horizontal Parallel. If this is out-of-spec, the
Dancer Arm will need to be removed, re-worked, and replaced.
5. Remove the indicator.
Chromira 56
F: TAKE-UP SIDE DANCER ROLLER FINAL PARALLEL CHECK
1. Set up the Thou Indicator to read the side-dead-center of the Take-Up Side Dancer Roller.
2. Perform the same Dancer Roller Horizontal Parallel reading as in step #3, part E. This
deviation should also be within .007.
Note: There is no adjustment for the Dancer Roller Horizontal Parallel. If this is out-of-spec,
the Dancer Arm will need to be removed, re-worked, and replaced.
3. Remove the indicator.
G: CHECK PAPER-TRACKING PERFORMANCE
1. Remove the paper form the machine, and double-check that it is rolled up perfectly. Ram
it into the floor to even out the wind. (Bang the end that will go against the motorized flange
on the floor.)
2. Re-load the paper onto the machine, making sure that the edge is aligned with the flange
on the Take-Up Side of the machine.
3. Advance the paper for a good distance, and watch the edge of the paper winding up on
the Take-Up Core. The surface formed by the rolling paper should be flat without ripples.
