Mappers Printers Test
These documents are designed to test the suitability of a colour printer for the reproduction of orienteering maps.
They also allow the optimisation of the printed map colours by adjusting colours within OCAD.

Note that the colour of any printing is dependant on the type of paper used. For all these tests it is important that
you use the exact paper intended for printing your orienteering maps.
The main purpose of this page is to test the printing of map colours as they are reduced in intensity. You should be looking
for a linear reduction in intensity with no noticeable change of colour (hue). It is quite common for some laser printers to have
problems with both linearity and colour when the intensity is less than about 30%. The best printers can produce almost
perfect results - linear fade and with no noticeable colour change.
The bottom section of this page is designed to test some of the typical orienteering map printing problems:-
Do the dots of the rough open with scattered trees symbol print clearly?
Can these dots be seen clearly behind the green lines?
Do the green lines of the undergrowth screen appear to be evenly spaced and all the same line thickness?
Do the green lines print the same over the rough open colour?
Do the brown contour lines look a constant width over each colour?
Does the apparent width of the contour line vary as the direction of the line changes?
Are the blue lines (streams and ditches) clearly visible over the '100%' green?
Do you get any small gaps (white) around the contours or the stream/ditch symbols?
The main section of the page is comprises a series of cross hair and ellipses - in each map colour - of increasing line
thickness from 0.05 to 0.40mm.
This will test the ability of the printer to print lines of a certain width, both horizontally, vertically and any angle in between. It is
quite common for the colours other than black to look as if they vary in width around the ellipse. Some printers struggle to
print the yellow in the finer line widths.
If you examine closely it is very common for the printed line width to increase in distinct steps about every 0.04mm. One
important one to check is the brown (contour) at 0.14mm which is the standard contour width for 1:15000 maps. It may be
necessary to print contours using 0.15mm to get a more consistent line quality!
The bottom section of the page is to test accuracy of line width and placement by printing 0.05mm lines at line spacing
increasing by 0.01mm, printed horizontal, vertical and on a diagonal. The black arrows indicate a gap of 0.05, 0.10, 0.15 and
0.20mm. If your printer is printing lines wider than nominal, no gaps will appear between lines until part way across each
block. Note this test can be significantly affected by the type (smoothness) of print paper that is used.
OCAD colour swatch printer setup file8.ocd
This OCAD8 file is designed to assist in the fine tuning of the OCAD8 colour table so that map colours are the best possible
match to the default Pantone colours as defined by the International Specification for Orienteering Maps (ISOM2000).
Open the file with OCAD8 and print on your printer. Using the IOF (ISOM 2000) / BOF colour swatch as reference, compare
the printed colours against the swatch. Adjust colours in the OCAD8 colour table ( Symbols | Colors ) and reprint until
you achieve a the best possible match.
For assessment of printed colours, you should ideally view the any printouts in daylight rather
than artificial light.
Note that the file has been setup so that it is possible to edit the numbers for each colour within the print - the print will then
be a record of the colours used to print it.
