Description
Technical Field

Background
The inkjet printing technology refers to a technology of ejecting ink droplets onto a printing medium through nozzles on a head to obtain images or characters, and mainly includes shuttle scan printing, one-time scan printing, and the like. For reciprocating scanning printing, in order to increase the height which can be covered by each scanning printing, a technical scheme of longitudinally splicing a plurality of spray heads is often adopted; for one-time scanning printing, the width of printing is increased by transversely splicing the spray heads. As shown in fig. 1, schematic diagrams of longitudinal splicing and transverse splicing of the spray heads in the arrangement direction of the spray nozzles are shown. The splicing mode can enable partial nozzles of the spray heads to overlap, and in the prior art, the eclosion treatment is often carried out on the image data of the splicing area (overlapping area) of the spray heads so as to achieve a better printing effect. However, the difference in the feathering effect of the spliced region of the spray head after the feathering treatment as shown in fig. 2 also easily occurs: too dark or too light.
The reason for this problem may be that the feathering effect is affected by factors such as the use of different amounts of ink, different materials, or different printing speeds at the time of printing, and the feathering effect is reduced when the amount of ink, the materials, or the printing speed is changed because of the lack of the function of adjusting the feathering effect in some printers, and the control software of other printers may provide the feathering effect adjusting function according to the amount of ink, the materials, or the like, but cannot intuitively and comparably confirm and select the optimal feathering effect because of the lack of the reference standard for adjusting the effect calibration, thereby affecting the image printing effect and reducing the printing quality.

Example 1
The embodiment of the invention provides a spray head splicing and feathering calibration method, which is suitable for a reciprocating scanning printer and a disposable scanning printer (Single-pass), wherein the reciprocating scanning printer and the disposable scanning printer both comprise a spray head group formed by a plurality of spray heads, partial nozzles among the spray heads are overlapped and spliced, and an ink is discharged to print an image.
In this embodiment, taking longitudinal splicing of the nozzles as an example, an ink-jet printing feathering calibration chart is printed, so as to perform feathering calibration on nozzles at overlapping positions when a plurality of nozzles in the nozzle group are spliced.
Referring to fig. 3, the method for calibrating the spray head spliced feathering includes the following steps:
step S1: acquiring eclosion calibration image data, and controlling a nozzle at least at an overlapping position to print the eclosion calibration image data according to preset printing parameters in an inkjet mode to obtain an eclosion calibration image, wherein the eclosion calibration image comprises a plurality of sub-eclosion calibration images, and the eclosion amplitude of at least one sub-eclosion calibration image in the plurality of sub-eclosion calibration images is different from that of the rest sub-eclosion calibration images;
step S2: acquiring a sub-eclosion calibration graph with eclosion effect meeting preset conditions in the eclosion calibration graph, and recording the sub-eclosion calibration graph as a reference eclosion calibration graph;
step S3: when the position of the reference sub-eclosion calibration chart is not at the preset position in the eclosion calibration chart, adjusting the preset printing parameters according to the position of the reference sub-eclosion calibration chart, and controlling the nozzles at least at the overlapped positions to print the eclosion calibration image data according to the adjusted preset printing parameters in an inkjet mode to obtain a new eclosion calibration chart;
step S4: and repeating the step S2 and the step S3 until the reference sub-eclosion calibration graph is positioned at a preset position in the eclosion calibration graph.
Specifically, in step S1, at least nozzles at overlapping positions in the head group are controlled to perform inkjet printing of feathering calibration image data according to preset printing parameters of the printer. Because the eclosion effect of the nozzles at the overlapping positions is mainly calibrated, the eclosion calibration graph can be obtained by only controlling the nozzles at the overlapping positions in the nozzle group formed by splicing a plurality of nozzles according to the preset printing parameters to print the eclosion calibration image data, or the eclosion calibration graph can be obtained by controlling all the nozzles in the nozzle group according to the preset printing parameters to print the eclosion calibration image data. The eclosion calibration image data may be input by a user or pre-stored in a printer memory module.
Preferably, the feathered calibration image data is generated from a feathered calibration vector image produced before printing. The eclosion calibration vector map comprises a plurality of sub-eclosion calibration vector maps. For a longitudinally spliced spray head, the sub-feathering calibration vector maps are preferably arranged in a horizontal direction, and the height and width of each sub-feathering calibration map are the same. For a transversely spliced spray head, the sub-feathering calibration vector maps are preferably arranged in a vertical direction, and the height and width of each sub-feathering calibration map are the same.
Preferably, the number of sub-feathered calibration vector images included in the feathered calibration vector images is an odd number. Of course, an even number is also possible. The odd number of sub-eclosion calibration vector images can better compare eclosion effects in the printed eclosion calibration images, so that the sub-eclosion calibration image with the best eclosion effect is selected.
Preferably, the sub-feathered calibration vector image consists of a rectangular color block and a numerical value, wherein the numerical value is used for representing the position of the corresponding sub-feathered calibration vector image in the feathered calibration vector image. As shown in FIG. 4, the generated feathered calibration vector image includes 11 sub-feathered calibration vector images, all of which are identical in width and height, and each rectangular color block is marked with a numerical value below, and the position of each sub-feathered calibration vector image in the feathered calibration vector image is standardized. The values that characterize the position may be above or below the rectangular color bar, or in the rectangular color bar, without limitation.
After the eclosion calibration vector diagram is manufactured, image processing is carried out on the eclosion calibration vector diagram, and eclosion calibration image data is generated. In this embodiment, the eclosion calibration vector map is subjected to image processing by RIP software: the eclosion calibration vector images are input into RIP software, the RIP software generates eclosion calibration image data according to the width and height of the eclosion calibration vector images and the designated ink quantity point type through a screening algorithm and the like, the eclosion calibration image data are dot matrix image data, and each sub eclosion calibration vector image corresponds to one sub eclosion calibration image data.
After the eclosion calibration image data is obtained, controlling a spray head to carry out ink jet printing on the eclosion calibration image data according to preset printing parameters to obtain an eclosion calibration graph. Preferably, the preset printing parameters at least include: the overlapping nozzle calibration adjustment parameters are used for adjusting the eclosion intensity during printing, and the larger the eclosion intensity is, the fewer ink points are, the fewer data are, and the shallower the ink quantity is; the smaller the feathering intensity, the more ink dots, the more data, and the ink amount is enriched. An overlapping nozzle calibration adjustment parameter corresponds to a feathering intensity, the smaller the parameter, the smaller the feathering intensity, and the larger the parameter, the larger the feathering intensity. In one embodiment, the preset printing parameters further comprise: any one, two or more of the material of the printing stock, the printing precision, the printing speed and the printing ink quantity. Any one of different printing material quality, printing precision, printing speed, printing ink quantity and the like can cause different printed feathering effects under the same overlapped nozzle calibration and adjustment parameters.
Before printing, setting preset printing parameters, and controlling at least nozzles at overlapping positions to obtain an eclosion calibration chart according to the data of the eclosion calibration image of the preset printing parameters in inkjet printing. In this embodiment, the feathering calibration image data is printed using the nozzle discharge ink of all channels in the head: the generated feathered calibration image data is transmitted to the printer, and printer control software assigns the feathered calibration image data to the corresponding nozzles. Illustratively, a feathering calibration map is printed using the heads H1 and H2; the single-column channels in H1 and H2 comprise 400 nozzles, wherein 391-400 rows in H1 overlap with 1-10 rows in H2, the eclosion calibration image data are distributed to all color channel nozzles of the spray heads H1 and H2 for printing, and each color channel prints the eclosion calibration image data once. Since the nozzles of the overlapping portion of the head H1 and the head H2 print image data of the same position in the feathering calibration image data, the image data of this position needs to be subjected to the feathering processing. The general eclosion calibration image data is printed on each color channel, so that the printing effect of each color channel is fused together to adjust the eclosion parameters, the scene of a real printing image is completely simulated, and a better eclosion calibration effect is obtained.
In addition, it is set that at least one of the sub-eclipse calibration image data is different in eclipse amplitude at the time of printing, and therefore the eclipse amplitude of the sub-eclipse calibration image data corresponding to the eclipse calibration image data is different from that of the other sub-eclipse calibration images. Preferably, the eclosion ranges of all the sub eclosion calibration graph data are different when printing is performed, so that the corresponding optimal eclosion range under the current preset printing parameters is obtained, the optimal eclosion range is stored corresponding to the current preset printing parameters, and the corresponding eclosion range can be directly called for eclosion treatment when the current preset printing parameters are used for printing subsequently, so that the optimal eclosion effect is obtained.
Further, the eclosion amplitude of the sub-eclosion calibration image data may be sequentially changed from small to large or from large to small so as to observe and judge the eclosion effect of each sub-eclosion calibration map.
Illustratively, as shown in fig. 4, the manufactured feathering calibration vector image includes 11 sub-feathering calibration vector images, after image processing, 11 sub-feathering calibration image data are generated, each color channel in the head prints the 11 sub-feathering calibration image data once, and when printing, as shown in fig. 5, the feathering amplitude of the sub-feathering calibration image data corresponding to the overlapping nozzle positions increases in sequence from small to large according to the position values thereof.
Fig. 6 shows a feathering calibration chart of the black channel finally printed. The eclosion calibration graph comprises a plurality of sub-eclosion calibration graphs, wherein the sub-eclosion calibration graphs are arranged in a horizontal direction, the heights and the widths of all the sub-eclosion calibration graphs are the same, and numerical values representing positions are marked below each sub-eclosion calibration graph. Because the eclosion amplitude of the image data corresponding to each sub-eclosion at the overlapped nozzle position is different, the eclosion effect of each sub-eclosion calibration image corresponding to the overlapped nozzle position obtained by printing is also different.
In step S2, a sub-eclosion calibration chart with eclosion effect satisfying a preset condition in the acquired eclosion calibration chart is acquired and is recorded as a reference sub-eclosion calibration chart, and the specific process is as follows:
the sub-eclosion calibration graph satisfying the preset condition refers to a sub-eclosion calibration graph with the eclosion effect being the best one of all the sub-eclosion calibration graphs. In the feathering calibration chart shown in fig. 6a, the feathering calibration chart corresponding to the value 2 has the best feathering effect, and the color band of white or black (darker color relative to the rest) is basically invisible to naked eyes. And (5) marking the sub-eclosion calibration graph corresponding to the value 2 as a reference sub-eclosion calibration graph.
In step S3, when the position of the reference sub-eclosion calibration chart is not at the preset position in the eclosion calibration chart, adjusting the preset printing parameters according to the position of the reference sub-eclosion calibration chart, and controlling the nozzles at least at the overlapping positions to print the eclosion calibration image data according to the adjusted preset printing parameters in an inkjet manner to obtain a new eclosion calibration chart;
the preset position herein refers to a position corresponding to a value of 0. Printing a printing object of a certain material under parameters such as printing precision, printing speed or printing ink quantity set in preset printing parameters, theoretically, if the reference sub-eclosion calibration chart is not at the position of 0 corresponding to the position where the numerical value of 0 should appear, adjusting overlapping nozzle calibration adjustment parameters in the preset printing parameters according to the numerical value of the position of the reference sub-eclosion calibration chart, and then reprinting eclosion calibration image data to obtain a new eclosion calibration chart.
And finally, repeating the step S2 and the step S3 until the reference sub-eclosion calibration graph is positioned at a preset position in the eclosion calibration graph.
And acquiring the position of the reference sub-eclosion calibration chart from the new eclosion calibration chart, and ending the calibration when the reference sub-eclosion calibration chart is positioned at a preset position in the eclosion calibration chart. As shown in fig. 6b, after the preset printing parameters are adjusted, the obtained reference sub-eclosion calibration chart is located at a position corresponding to the value 0 in the eclosion calibration chart, because the overlapped nozzle calibration adjustment parameters in the preset printing parameters are modified, the value of the modified overlapped nozzle calibration adjustment parameters is considered to obtain the optimal eclosion effect for the current printing stock, the current modified preset printing parameters are saved, and the corresponding preset printing parameters can be directly used for eclosion treatment during the subsequent printing of the printing stock, so that the optimal eclosion effect is obtained.
In another embodiment, any one, two or more of the material of the printing stock (corresponding to the need to replace the printing stock), the printing precision, the printing speed, the type of ink dots or the amount of printing ink in the preset printing parameters can be adjusted, and then the eclosion calibration image data is reprinted to obtain a new eclosion calibration graph. And step S2 and step S3 are repeated until the reference sub-eclosion calibration graph is positioned at a preset position in the eclosion calibration graph, the current modified preset printing parameters are stored, and corresponding printing precision, printing speed, printing ink quantity and overlapping nozzle calibration adjustment parameters can be directly used for subsequent printing of a certain type of printing stock so as to obtain the optimal eclosion effect.
In summary, according to the method for calibrating the spliced spray heads, the spliced spray heads are controlled to obtain the eclosion calibration chart according to the data of the eclosion calibration images of the inkjet printing of the preset printing parameters, the reference eclosion calibration chart with the optimal eclosion effect is obtained from the eclosion calibration chart, the preset printing parameters are adjusted according to the position of the reference eclosion calibration chart, and then the eclosion calibration chart is reprinted until the obtained reference eclosion calibration chart is located at the preset position in the eclosion calibration chart, and calibration is finished. The embodiment of the invention provides a technical scheme capable of rapidly calibrating the feathering of the nozzles of the overlapped part of the spray heads, which can rapidly, intuitively and conveniently calibrate the corresponding optimal feathering effect under the printing parameters of different printing objects, different printing precision, different printing speeds, different printing ink amounts, different ink dot types and the like, thereby ensuring that the printer obtains the optimal printing image effect under different printing parameters.
