Definitions

  • the invention relates to a method for matching the writing nozzles of an ink print head according to the preamble of patent claim 1.
  • An essential component of an ink writing device is the ink print head.
  • This contains a large number of writing nozzles, each of which is assigned an individually controllable converter element.
  • the writing nozzles are connected to an ink supply system and end on the side facing a recording medium in outlet openings which are arranged there in one or more rows.
  • character information is taken from a character generator and transferred to a pixel memory, in which the character to be displayed is electronically depicted, so to speak.
  • the converter elements are controlled and the characters are built up in a grid pattern on the recording medium via printer electronics.
  • a character matrix it is built up in a character matrix, the horizontally running grid columns of which are referred to as traces, the vertically running columns of which are referred to as print columns.
  • traces the horizontally running grid columns of which are referred to as traces
  • print columns the vertically running columns of which are referred to as print columns.
  • a character matrix can have 32 tracks and 96 printing columns.
  • DE-OS 34 38 675 proposes a method for avoiding alignment errors when printing with multiple nozzles. This is to prevent registration errors from occurring when printing an image, which are due to the positional deviation between the color or ink output by the respective nozzles with respect to the direction of the carriage carrying the nozzles.
  • the positional difference between the color droplets from the respective nozzles with respect to the direction of the carriage movement is determined, in order to determine the times for the start of the printing process with the ink from the respective nozzles, based on the determined difference.
  • the object of the invention is to provide a way of comparing the writing nozzles of an ink print head without the need for additional aids, in which the number of writing nozzles to be compared does not play a decisive role and with which not only the tolerances of the components and the transducer or the Parameters changing ink properties but also the parameters acting on the entire writing device, such as carriage drive, distance between recording medium and writing nozzles, inclined position of the printhead etc. are also recorded.
  • FIG. 1 shows on the right the front part of a print head DK, at which a total of 32 writing nozzles D1 to D32 end.
  • the outlet openings of the writing nozzles D1 to D32 are arranged here in four vertical columns, each with eight writing nozzles.
  • characters and / or patterns can be displayed in a grid pattern in the character matrix ZM shown on the left.
  • the character matrix ZM also has 32 lines or tracks, corresponding to the 32 writing nozzles D1 to D32. 96 printing columns are provided in the horizontal direction. So that a very high resolution can be achieved for the representation of characters or patterns, so that, for. B. Text characters shown correspond in their quality to the characters printed with type printing units.
  • Fig. 2 shows an example of a row of ink droplets applied in the vertical direction.
  • the illustration on the left shows the ideal case where all ink dots in the row are exactly in print column 1 of the characters matrix ZM ,, that is, they lie exactly below each other.
  • This case is ideal because all the writing nozzles, in the example D1 to D12, are involved in the construction of the row of dots shown and practically always more or less large tolerances, as mentioned at the beginning, cause a more or less large offset of the ink dots.
  • the droplet row shown on the right in FIG. 2 shows a practical example of such a droplet offset.
  • the writing nozzles D1 to D12 are activated taking into account the movement of the print head DK relative to a recording medium and the geometrical arrangement of the outlet openings of the writing nozzles D1 to D12 in the print head DK at precisely defined desired times, and ink droplets are also expelled at these times.
  • ink droplets ejected by the writing nozzles D1, D5, D9 and D11 and thus the ink dots of the tracks 1, 5, 9 and 11 are located in the print column 1 of the character matrix ZM. All ink dots of the other tracks have a more or less large droplet offset. It can be seen that the typeface is considerably disturbed.
  • FIG. 3 shows the print column grid DSR in the first line, it being assumed here that the character matrix ZM comprises 96 print columns, the spacing of which is 1/960 ⁇ in each case. This results in a character width of 1/10 ⁇ .
  • the DRM pressure pulse pattern is shown in the second line. Assuming that one and the same writing nozzle can eject a droplet of ink at a distance of 1/120 jeweils, the pressure pulses are at a distance of 1/120 ⁇ .
  • the third line shows the selected print times on a record carrier brought vertical lines of DRSC, as they would ideally occur.
  • the method according to the invention is described below with reference to FIGS. 3 and 4. It consists of the following steps.
  • the line pattern SCI according to line 5 of FIG. 3 is printed out in a printer run for each individual nozzle D1 to D32.
  • This line pattern SCI consists of a series of vertical rows of dots formed by ink droplets from one and the same writing nozzle.
  • the writing nozzle in question is controlled for droplet ejection in a printing pulse raster DRM, which is made available by a clock disk T connected to the drive motor M for the movement of the printing head DK.
  • the pressure column grid DSR is also synchronized with the pressure key grid DRM.
  • the pressure column grid DSR has a division of 1/960 ⁇ and that a writing nozzle can be acted upon with a pressure pulse at a grid spacing of 1/120 ⁇ , so in the section shown the pressure pulses are each delivered in the manner shown in line 2 of FIG. 3 within a character matrix ZM comprising 96 printing raster columns.
  • droplets are not ejected with every pressure pulse in order to display the line pattern.
  • line 3 of FIG. 3 shows, droplet ejection is effected with the first, the eighth, the sixteenth, etc. pressure pulse.
  • the line pattern is printed on the record carrier P by multiple passes and correspondingly finely divided feed of the record carrier.
  • Line 4 shows the line pattern SCS without considering a droplet offset VS. Due to the tolerances described at the beginning of components, of mechanical parts of the writing device, etc., however, there are deviations between the positions determined by the pressure key pattern DRM and the actual impact points of the ink droplets.
  • Line 5 shows the actually printed line patterns SCI. The distances can be called the difference between a target and an actual position. These distances can already have different values for one and the same writing nozzle for forward and backward running (in so-called bidirectional printing). The values continue to differ from writing nozzle to writing nozzle. If the printer advance described with reference to FIG. 3 is carried out for each nozzle in the forward and backward direction, such a line pattern is also available for each nozzle for both writing directions.
  • the measures provided for the adjustment of the individual writing nozzles provide for a scanning run.
  • the line pattern is scanned with an optical sensor AB arranged on the print head DK during a pass through the print head DK, again separately for both writing directions R, L.
  • the scanner AB which works in the print column grid DSR, is synchronized with the print cycle grid DRM in order to obtain a common fixed point for determining the droplet offset VS.
  • the sampled values AW determined by the scanner AB during a scan run represent the actual position
  • the values determined by the push-button matrix DRM represent the desired position.
  • the values AW determined by the scanner are practically a sequence of "o” and "1" values These values enable a central control ZS to offset VS between the target and the actual position for each individual writing nozzle D1 to D32 exactly up to the subdivision of the printing column grid To calculate DSR.
  • Line 5 of FIG. 3 shows the actual printing position SCI of each vertical line printed during the printer advance.
  • the center of the ink dots forming the vertical line is assumed. In the example according to FIG. 3, this is designated with print position P1 (line 4) and print position P2 (line 5).
  • print position P1 line 4
  • print position P2 line 5
  • the value VS thus calculated represents the exact droplet offset, which then z. B.
  • the stored values of the droplet offset VS for each individual writing nozzle D1 to D32 separately in the forward and reverse writing directions are now available to the pixel memory BS of the ink writing device for a printing or recording operation carried out during normal operation of the ink writing device.
  • a correction is made for each writing nozzle D1 to D32 in accordance with that in the memory VSP stored value for the droplet offset VS.
  • predistortion takes place in accordance with the printing direction R, L and the measured droplet offset VS.
  • Line 6 of FIG. 3 shows the scanning areas ABB and the transition areas UEB between two “actual” positions of the ink droplets, the scanning beginning at the time TA and ending at the time TE.
  • the transition area UEB which lies between the scanning areas of two writing nozzles, is not included in the calculation of the nozzle specification / droplet offset.
  • FIG. 4 An exemplary embodiment for carrying out the method according to the invention is shown in FIG. 4.
  • the exemplary embodiment contains the essential parts of an ink writing device necessary for understanding the invention. Specifically, it is a matter of the print head DK, which is attached to a writing carriage (not shown here), which in turn is moved back and forth in the line direction in front of a recording medium P by means of a drive motor M. The printing of characters or the representation of patterns takes place bidirectionally, ie during the movement of the print head DK to the right R and to the left L.
  • the ink writing device also has a central control ZS, a character generator ZG, a pixel memory BS and printer electronics DE.
  • the central control ZS is provided with the push-button raster DRM via a clock disk T assigned to the drive motor M.
  • the character generator ZG contains, for example, 256 different characters which can be addressed in accordance with the input data ED.
  • the character information for a specific character to be printed then arrives in the pixel memory BS, where the character is electronically mapped, so to speak. From there, the character information is transferred to the printer electronics DE. This is done under the control of the pressure column grid DSR.
  • the printer control unit DE is also supplied with the print key raster DRM by the central control ZS, so that the control of the individual writing nozzles takes place at the right time depending on the position of the print head DK.
  • a barcode is also printed in the manner described. For this purpose, corresponding character information can be contained in the character generator ZG, it being ensured that the printing of this character information takes place in each case through a single writing nozzle.
  • An optical sensor AB hereinafter called a scanner, is assigned to the print head DK. This is moved bidirectionally together with the print head DK. The bar code recorded during the printer run is scanned and the scanning values AW are transmitted to the central control ZS as the "actual" position SCI. There, the pressure cycle raster DRM emitted by the clock disk T is also available as the “target” position SCS. The value for the droplet offset VS is determined therefrom in a comparison circuit V. This value is entered for each individual writing nozzle in a memory VSP, which is preferably designed as RAM.
  • the value for the droplet offset VS contained in the memory VSP for the individual writing nozzles is fed to the pixel memory BS as the distortion value VW.
  • predistortion takes place in accordance with the printing direction and the measured droplet offset VS.
  • the invention was explained on the basis of an example in which a writing line in the forward direction and a writing line in the backward direction are covered with a defined bar code and then scanned for the individual writing nozzles.
