Description

Technical Field

[0001] The present invention relates to the technical field of inkjet printing, and particularly to a printing method, device, equipment and storage medium for eliminating overlapping splicing tracks. Background Art

[0002] Inkjet printing is a contactless, pressureless and plate-free printing technology. Ink droplets are ejected onto a printing medium through nozzles in a print head to obtain images or texts. The reciprocating scanning printing technology is a commonly used technology in the current inkjet printing field. Reciprocating scanning printing is also called multi-pass scanning printing. Multi-pass scanning printing means that each unit of the image to be printed needs to be interpolated multiple times to complete printing. Each unit is composed of multiple pixel points. For example, in 2-pass scanning printing, each unit is composed of 2 pixel points, and in 3-pass scanning printing, each unit is composed of 3 pixel points. In reciprocating scanning printing, in order to improve printing efficiency, several print heads are usually longitudinally spliced to form a print head group for printing, as follows Figure 1a and 1b shown, print head 1, print head 3, and print head 5 are spliced together to form a print head group with two splicing positions; print head 2 and print head 4 are longitudinally spliced to form a print head group with one splicing position. This print head group is equivalent to a logical print head with a greater printing height. When the spliced print head group is printing, due to the different ink ejection times of the nozzles in each print head and the deviation of the ink drop landing positions, it is easy to cause splicing tracks at the printing positions corresponding to the splicing positions of the print head group. During the reciprocating scanning printing process, the positions of these splicing tracks are prone to overlap, resulting in a more obvious splicing track phenomenon, as Figure 2 shown. Using the print head group in Figure 1a for reciprocating scanning printing, during the first scanning printing, the printing position b corresponding to the splicing position of print head 1 and print head 3 partially overlaps with the printing position c corresponding to the splicing position of print head 3 and print head 5 during the second scanning printing. During the third scanning printing, the printing position e corresponding to the splicing position of print head 3 and print head 5 overlaps with the printing position d corresponding to the splicing position of print head 1 and print head 3 during the second scanning printing. Or as Figure 3 shown, using the print head group formed by splicing print head 2 and print head 4 for printing, when the stepping height is small, there will also be partial overlap at the printing positions corresponding to the splicing positions during the first scanning printing and the second scanning printing, resulting in deepening of the splicing tracks and seriously affecting the image printing quality.

[0050] Embodiment 1

[0051] An embodiment of the present invention provides a printing method for eliminating overlapping splicing lanes, which is applicable to reciprocating scanning inkjet printing applications. The reciprocating scanning printing device at least includes a printhead group formed by splicing two printheads, and each printhead at least includes a column of nozzles. The nozzles eject ink droplets onto a printing medium to form an image.

[0052] Please refer to Figure 4 , and the printing method for eliminating overlapping splicing lanes specifically includes the following steps:

[0053] S1: Obtain the printing height, the original feathering height, and the original stepping height;

[0054] S2: Obtain the printing area corresponding to the splicing position of the printhead group during printing according to the original feathering height and the original stepping height, which is the first splicing lane;

[0055] S3: Adjust the original feathering height and the original stepping height according to the position of the first splicing lane to obtain an updated feathering height and an updated stepping height;

[0056] S4: Control the printhead group to perform the next printing according to the updated feathering height and the updated stepping height. When performing the next printing according to the updated feathering height and the updated stepping height, the printing area corresponding to the splicing position of the printhead group does not overlap with the first splicing lane.

[0057] Specifically, when performing reciprocating scanning printing, it is necessary to determine the printing mode of reciprocating scanning according to the image accuracy of the image to be printed, the printing accuracy of the printing device, etc. The determination of the printing mode here includes at least the number of scans. Exemplarily, if the first image accuracy is 720 dpi×720 dpi and the printing accuracy is 360 dpi×360 dpi, then the number of scans is 4, that is, the printing mode is 4PASS printing. The original feathering height and the original stepping height are the feathering height and the stepping height in the current scanning printing. Among them, the printing height can be calculated according to the original feathering height, the original stepping height, and the number of scans, that is, the printing height is equal to the original stepping height multiplied by the number of scans plus the original feathering height. After determining the original feathering height and the original stepping height, the printing area corresponding to the nozzle group splicing position during the current scanning printing can be obtained according to these printing parameters, denoted as the first splicing lane. In order to avoid partial or complete overlap of the printing positions corresponding to the nozzle group splicing position in the next scanning printing, in the embodiment of the present invention, before the next scanning printing, the original feathering height and the original stepping height are adjusted according to the position of the first splicing lane to obtain the updated feathering height and the updated stepping height, and then the nozzle group is controlled to perform the next scanning printing according to the updated feathering height and the updated stepping height, so that the printing position corresponding to the nozzle group splicing position does not overlap with the first splicing lane. Similarly, after completing the next scanning printing, the feathering height and the stepping height are adjusted again according to the printing position corresponding to the nozzle group splicing position in the next scanning printing, so that the printing position corresponding to the nozzle group splicing position in the next-next scanning printing does not overlap with the printing position corresponding to the nozzle group splicing position in the next scanning printing. And so on until the printing is completed. In the embodiment of the present invention, the feathering height and the stepping height are dynamically adjusted according to the printing position corresponding to the nozzle group splicing position, so as to avoid overlapping printing of the printing position corresponding to the nozzle group splicing position, that is, the splicing lane, in reciprocating scanning printing, eliminate the influence caused by the overlapping of the splicing lanes, and improve the image printing quality.

[0058] In one embodiment, the adjusting the original feathering height and the original stepping height according to the printing height and the position of the first splicing lane to obtain the updated feathering height and the updated stepping height includes:

[0059] S21: Obtain the first adjusted feathering height according to the original feathering height and the preset maximum feathering height;

[0060] S22: Obtain the first adjusted stepping height according to the first adjusted feathering height and the printing height;

[0061] S23: Obtain the printing position corresponding to the nozzle group splicing position during printing, denoted as the second splicing lane, according to the first adjusted feathering height and the first adjusted stepping height;

[0062] S24: When there is partial or complete overlap between the first splicing path and the second splicing path, repeat steps S21 - S23 until the first splicing path and the second splicing path do not overlap, and obtain the current first adjusted feathering height and the first adjusted stepping height, which are the updated feathering height and the updated stepping height.

[0063] In this embodiment, the non - overlap of the splicing paths is achieved by adjusting the feathering height and then adjusting the stepping height. Specifically, set the value range of the feathering height adjustment. Denote the original feathering height as Eo and the preset maximum feathering height as Emax. In one embodiment, the maximum feathering height is half of the height of the printhead group. Here, the height of the printhead group refers to the maximum print height that the printhead group can achieve in one scan along the printing direction. In other embodiments, the maximum preset feathering height can also be adjusted according to the actual situation, for example, less than or greater than half of the height of the printhead group. Preferably, the value range is set between the original feathering height and the preset maximum feathering height, that is, [Eo, Emax]. The first adjusted feathering height takes a value within it. Exemplarily, the value of the first adjusted feathering height is Eo + 1. According to the first adjusted feathering height, obtain the first adjusted stepping height. Among them, the first adjusted feathering height and the first adjusted stepping height satisfy the following formula:

[0064] PRINTH = PASSH * PASSMODE + ECLPH;

[0065] Where, PRINTH is the printing height, PASSH is the first adjusted stepping height, ECLPH is the first adjusted feathering height, and PASSMODE is the number of scans in the current printing mode. Exemplarily, when the current printing mode is 4PASS printing, then PASSMODE is 4, and we can get:

[0066] PASSH = (PRINTH – ECLPH) / PASSMODE;

[0067] The first adjustment feathering height and the printing height are known, and the first adjustment step height can be obtained according to the formula. According to the first adjusted feathering height and the first adjusted step height, simulated printing can be performed to determine the printing position corresponding to the splicing of the nozzle group when the first adjusted feathering height and the first adjusted step height are scanned and printed next time, that is, the second splicing path. If the second splicing path does not overlap with the first splicing path, the first adjusted feathering height at this time is recorded as the updated feathering height. If the second splicing path overlaps with the first splicing path (partial overlap or complete overlap), it means that the first adjusted feathering height and the first adjusted step height do not meet the requirements, then the value of the first adjusted feathering height is re-obtained from the above value range. Exemplarily, the value of the first adjusted feathering height is adjusted to Eo+2, and then the corresponding first adjusted step height is obtained according to the adjusted first adjusted feathering height, and the position of the second splicing path is obtained during simulated printing... Repeat the above process until the obtained second splicing path and the first splicing path do not overlap, then the first adjusted feathering height and the first adjusted feathering height at this time are recorded as the updated feathering height and the updated step height. In practical applications, the value step length of the first feathering height adjustment can be adjusted in real time according to the simulated printing situation, and is not limited to taking values ​​in sequence according to the value step length 1 as in the present embodiment. In other embodiments, the optimal feathering height adjustment step length can be calculated according to the position of the second splicing track after the simulated printing is performed according to the first feathering height adjustment and the first feathering height adjustment, and the updated feathering height can be directly obtained according to the adjustment step length, thereby reducing the cycle process and improving the printing efficiency. After obtaining the updated feathering height and the updated step height, as shown in FIG. Figure 5 As shown, the step height is adjusted by adjusting the feathering height so that the printing position corresponding to the joint of the nozzle groups in the next scanning printing does not overlap with the printing position corresponding to the joint of the nozzle groups in the previous scanning printing.

[0068] In another embodiment, adjusting the original feathering height and the original stepping height according to the printing height and the position of the first splicing track, and obtaining the updated feathering height and the updated stepping height comprises:

[0069] S31: acquiring a second adjusted step height according to the original step height and a preset maximum step height;

[0070] S32: acquiring a second adjusted feathering height according to the second adjusted step height and the printing height;

[0071] S33: acquiring a printing position corresponding to the joint of the nozzle groups during printing according to the second adjustment step height and the second adjustment feathering height, and recording it as a third joint path;

[0072] S34: When there is partial or complete overlap between the first splicing lane and the third splicing lane, repeat steps S31 - S33 until the first splicing lane and the third splicing lane do not overlap, and obtain the current second adjusted feathering height and the second adjusted stepping height, which are the updated feathering height and the updated stepping height.

[0073] In this embodiment, the non - overlap of the splicing lanes is achieved by adjusting the stepping height and then adjusting the feathering height. Specifically, set the value range of the stepping height adjustment. Denote the original stepping height as Po and the preset maximum stepping height as Pmax. In one embodiment, the maximum stepping height is the height of the printhead group, where the height of the printhead group refers to the maximum printing height that the printhead group can achieve in one scan along the printing direction. In other embodiments, the maximum preset stepping height can also be adjusted according to the actual situation. Preferably, the value range is set between the original stepping height and the preset maximum stepping height, that is, [Po, Pmax], and the second adjusted stepping height takes a value therein. Exemplarily, the value of the second adjusted stepping height is Po + 1. Obtain the second adjusted feathering height according to the second adjusted stepping height. Among them, the second adjusted feathering height and the second adjusted stepping height satisfy the following formula:

[0074] PRINTH = PASSH' * PASSMODE + ECLPH';

[0075] Where PRINTH is the printing height, PASSH' is the second adjusted stepping height, ECLPH' is the second adjusted feathering height, and PASSMODE is the number of scans in the current printing mode. Exemplarily, if the current printing mode is 2PASS printing, then PASSMODE is 2, and we can get:

[0076] ECLPH' = PRINTH - PASSH' * PASSMODE;

[0077] The second adjusted step height and the printing height are known. According to this formula, the second adjusted feathering height can be obtained. Based on the second adjusted step height and the second adjusted feathering height, simulated printing can be performed to determine the printing position corresponding to the joint of the nozzle groups during the next scan printing at the second adjusted feathering height and the second adjusted step height, which is the third splicing path. If the third splicing path does not overlap with the first splicing path, the second adjusted step height at this time is recorded as the updated step height. If the third splicing path overlaps with the first splicing path (partially or completely), it indicates that the second adjusted step height and the second adjusted feathering height do not meet the requirements. Then, a value for the second adjusted step height is re-obtained from the above value range. Exemplarily, the value of the second adjusted step height is adjusted to Po + 2, and then the corresponding second adjusted feathering height is obtained based on the adjusted second adjusted step height. The position of the third splicing path is obtained by performing simulated printing... The above process is repeated until the obtained third splicing path and the first splicing path do not overlap. Then, the second adjusted step height and the second adjusted feathering height at this time are recorded as the updated step height and the updated feathering height. In practical applications, the value step size of the second adjusted step height can be adjusted in real time according to the situation of simulated printing, and it is not limited to sequentially taking values with a value step size of 1 as in this embodiment. In other embodiments, after performing simulated printing based on the second adjusted step height and the second adjusted feathering height, the optimal adjustment step size of the step height can be calculated according to the position of the third splicing path, and the updated step height can be directly obtained according to this adjustment step size, reducing the loop process and thus improving the printing efficiency. After obtaining the updated feathering height and the updated step height, as Figure 6 shown, by adjusting the feathering height to adjust the step height, the printing position corresponding to the joint of the nozzle groups during the next scan printing does not overlap with the printing position corresponding to the joint of the nozzle groups during the previous scan printing.

[0078] It should be noted that when performing the next scan printing, since the updated step feathering height and the updated step height are inconsistent with the original feathering height and the original step height, the corresponding printing data for the next scan printing needs to be processed according to the updated step height and the updated feathering height. For example, the position and height of the printing data for the next scan printing in the printing data of the entire image to be printed are obtained according to the updated step height, the corresponding printing data is extracted and feathering processing is performed according to the updated feathering height, and then the feathering-processed printing data is sent to the nozzle columns in the nozzle group for printing.

[0079] In summary, the printing method for eliminating overlapping splicing lanes provided by the embodiments of the present invention includes obtaining a printing height, an original feathering height, and an original stepping height; obtaining a printing area corresponding to the splicing position of the nozzle group during the current scanning and printing according to the original feathering height and the original stepping height, which is denoted as the first splicing lane; adjusting the original feathering height and the original stepping height according to the printing height and the position of the first splicing lane to obtain an updated feathering height and an updated stepping height; controlling the nozzle group to perform the next scanning and printing according to the updated feathering height and the updated stepping height, wherein the printing area corresponding to the splicing position of the nozzle group during the next scanning and printing according to the updated feathering height and the updated stepping height does not overlap with the first splicing lane. The method of the present invention dynamically adjusts the feathering height and the stepping height of the next scanning and printing according to the printing position corresponding to the splicing position of the nozzle group during the current scanning and printing, thereby avoiding overlapping printing of the printing position corresponding to the splicing position of the nozzle group, i.e., the splicing lane, in the reciprocating scanning and printing, eliminating the influence caused by the overlapping of the splicing lanes, and improving the image printing quality.
