Description

Technical Field

[0001] This invention relates to the field of inkjet printing technology, and in particular to a printing method, apparatus, device, and storage medium for eliminating overlapping stitching lines. Background Technology

[0002] Inkjet printing is a contactless, pressureless, and plate-free printing technology that uses nozzles in a printhead to eject ink droplets onto a printing medium to obtain images or text. Reciprocating scanning printing technology is currently the most commonly used technology in the inkjet printing field. Also known as multi-pass scanning printing, multi-pass scanning printing means that each unit of the image to be printed must be interpolated multiple times to complete the printing process. Each unit consists of multiple pixels; for example, in 2-pass scanning printing, each unit consists of 2 pixels, and in 3-pass scanning printing, each unit consists of 3 pixels. In reciprocating scanning printing, to improve printing efficiency, several printheads are usually vertically joined together to form a printhead group, as shown below. Figure 1a and 1b As shown, printheads 1, 3, and 5 are joined together to form a printhead group with two joints; printheads 2 and 4 are joined vertically to form a printhead group with one joint, which is equivalent to a logic printhead with a larger printing height. During printing, due to the different ink ejection times of the nozzles in each printhead, the ink droplet landing positions deviate, easily leading to splicing lines at the printing positions corresponding to the printhead group joints. In reciprocating scanning printing, these splicing lines tend to overlap, causing more noticeable splicing line phenomena, such as... Figure 2 As shown, using Figure 1a The printhead assembly performs reciprocating scanning printing. During the first scan, the printing position b corresponding to the junction of printhead 1 and printhead 3 partially overlaps with the printing position c corresponding to the junction of printhead 3 and printhead 5 during the second scan. During the third scan, the printing position e corresponding to the junction of printhead 3 and printhead 5 overlaps with the printing position d corresponding to the junction of printhead 1 and printhead 3 during the second scan. Or, as... Figure 3 As shown, when printing with a printhead assembly consisting of printhead 2 and printhead 4, if the step height is small, the corresponding printing positions at the splicing point will partially overlap during the first and second scan printing, resulting in a deeper splicing line and seriously affecting the image printing quality.

[0050] Embodiment one

[0051] The embodiment of the present application provides a printing method for eliminating overlapping spliced tracks, which is suitable for reciprocating scanning inkjet printing application, and a reciprocating scanning printing device at least includes a nozzle group spliced by two nozzles, each nozzle at least includes a column of nozzles, and the nozzles spray ink droplets on a printing medium to form an image.

[0052] Please refer to Figure 4 The printing method for eliminating overlapping spliced tracks specifically includes the following steps:

[0053] S1: acquiring a printing height, an original feathering height and an original stepping height;

[0054] S2: acquiring a printing area corresponding to a spliced position of a nozzle group at a printing time according to the original feathering height and the original stepping height, that is, a first spliced track;

[0055] S3: adjusting the original feathering height and the original stepping height according to a position of the first spliced track, and acquiring an updated feathering height and an updated stepping height;

[0056] S4: controlling the nozzle group to perform next printing according to the updated feathering height and the updated stepping height, wherein a printing area corresponding to the spliced position of the nozzle group at the next printing time is not overlapped with the first spliced track.

[0057] Specifically, when performing the reciprocating scanning printing, a printing mode of the reciprocating scanning needs to be determined according to an image precision of a to-be-printed image, a printing precision of a printing device and the like. The determination of the printing mode at least includes a scanning times. For example, when the first image precision is 720 dpi x 720 dpi and the printing precision is 360 dpi x 360 dpi, the scanning times is 4, that is, the printing mode is 4PASS printing. The original feathering height and the original step height are the feathering height and the step height in the current scanning printing. The printing height can be calculated according to the original feathering height, the original step height and the scanning times, that is, the printing height is equal to the original step height multiplied by the scanning times plus the original feathering height. After the original feathering height and the original step height are determined, the printing area corresponding to the joint of the printhead group in the current scanning printing can be obtained according to the printing parameters, which is recorded as the first joint. In order to avoid the printing position corresponding to the joint of the printhead group in the next scanning printing being partially overlapped or completely overlapped, in the embodiment of the present application, before the next scanning printing, the original feathering height and the original step height are adjusted according to the position of the first joint to obtain an updated feathering height and an updated step height, and then the next scanning printing is controlled according to the updated feathering height and the updated step height, so that the printing position corresponding to the joint of the printhead group is not overlapped with the first joint. Similarly, after the next scanning printing is completed, the feathering height and the step height are adjusted again according to the printing position corresponding to the joint of the printhead group in the next scanning printing, so that the printing position corresponding to the joint of the printhead group in the scanning printing after the next scanning printing is not overlapped with the printing position corresponding to the joint of the printhead group in the next scanning printing. By analogy, until the printing is completed. In the embodiment of the present application, the feathering height and the step height are dynamically adjusted according to the printing position corresponding to the joint of the printhead group, so as to avoid the overlapping printing of the joint of the printhead group in the reciprocating scanning printing, eliminate the influence of the overlapping of the joint and improve the image printing quality.

[0058] In one embodiment, the adjusting the original feathering height and the original step height according to the printing height and the position of the first joint to obtain an updated feathering height and an updated step height comprises:

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

[0060] S22: obtaining a first adjusted step height according to the first adjusted feathering height and the printing height;

[0061] S23: obtaining a printing position corresponding to the joint of the printhead group in the printing as a second joint according to the first adjusted feathering height and the first adjusted step height;

[0062] S24: When the first splicing path and the second splicing path have partial overlap or complete overlap, repeating steps S21-S23 until the first splicing path and the second splicing path do not overlap, obtaining the current first adjusted feathering height and the first adjusted step height, that is, the updated feathering height and the updated step height.

[0063] In the embodiment, the non-overlapping of the splicing path is realized by adjusting the feathering height and then adjusting the step height. Specifically, a value range of the feathering height adjustment is set, the original feathering height is denoted as Eo, and the preset maximum feathering height is denoted as Emax. In an embodiment, the maximum feathering height is half of the height of the nozzle group, where the height of the nozzle group refers to the maximum printing height that can be achieved by the nozzle group in one scanning in the printing direction. In other embodiments, the maximum preset feathering height can also be adjusted according to actual conditions, for example, less than half of the height of the nozzle group or greater than half of the height of the nozzle group. Preferably, the value range is set between the original feathering height and the preset maximum feathering height, that is, [Eo, Emax], and the first adjusted feathering height is taken from the value range. Exemplarily, the value of the first adjusted feathering height is Eo+1, and the first adjusted step height is obtained according to the first adjusted feathering height, where the first adjusted feathering height and the first adjusted step height satisfy the following formula:

[0064] PRINTH = PASSH * PASSMODE + ECLPH;

[0065] Wherein, PRINTH is the printing height, PASSH is the first adjusted step height, ECLPH is the first adjusted feathering height, and PASSMODE is the number of scans in the current printing mode. Exemplarily, the current printing mode is 4PASS printing, and then PASSMODE is 4, and the following can be obtained:

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

[0067] The first adjustment feathering height and the first adjustment printing height are known, and the first adjustment step height can be obtained according to the formula. According to the first adjustment feathering height and the first adjustment step height, the simulation printing can be performed, and the printing position corresponding to the nozzle group joint in the next scanning printing is determined, that is, the second joint path. If the second joint path and the first joint path do not overlap, the first adjustment feathering height at this time is recorded as the updated feathering height. If the second joint path and the first joint path overlap (partially overlap or completely overlap), it indicates that the first adjustment feathering height and the first adjustment step height do not meet the requirements, and then the value of the first adjustment feathering height is re-obtained from the above value range. For example, the value of the first adjustment feathering height is adjusted to Eo+2, and then the corresponding first adjustment step height is obtained according to the adjusted first adjustment feathering height. The simulation printing is performed to obtain the position of the second joint path. The above process is repeated until the second joint path and the first joint path do not overlap, and then the first adjustment feathering height and the first adjustment feathering height at this time are recorded as the updated feathering height and the updated step height. In actual application, the value step of the first adjustment feathering height can be adjusted in real time according to the simulation printing, and is not limited to the value step of 1 in the embodiment. In other embodiments, the best adjustment step of the feathering height can be calculated according to the position of the second joint path after the simulation printing is performed according to the first adjustment feathering height and the first adjustment feathering height, and the updated feathering height is directly obtained according to the adjustment step, so as to reduce the loop process and improve the printing efficiency. After the updated feathering height and the updated step height are obtained, the printing position corresponding to the nozzle group joint in the next scanning printing is adjusted feathering height, as shown in FIG. 10. Figure 5 The printing position corresponding to the nozzle group joint in the next scanning printing is adjusted feathering height, as shown in FIG. 10.

[0068] In another embodiment, the adjusting the original feathering height and the original step height according to the printing height and the position of the first joint path to obtain an updated feathering height and an updated step height comprises:

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

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

[0071] S33: obtaining a printing position corresponding to a nozzle group joint in printing according to the second adjustment step height and the second adjustment feathering height, and recording as a third joint path;

[0072] S34: When the first stitching path and the third stitching path have partial overlap or complete overlap, repeating steps S31-S33 until the first stitching path and the third stitching path do not overlap, obtaining the current second adjustment feathering height and the second adjustment step height, which are the updated feathering height and the updated step height.

[0073] In the embodiment, the non-overlapping of the stitching paths is achieved by adjusting the step height and then adjusting the feathering height. Specifically, the value range of the step height adjustment is set, denoted as Po, the preset maximum step height is Pmax, and in an embodiment, the maximum step height is the height of the nozzle group, which refers to the maximum printing height that can be achieved by the nozzle group in one scanning along the printing direction. In other embodiments, the maximum preset step height can also be adjusted according to the actual situation. Preferably, the value range is set between the original step height and the preset maximum step height, i.e. [Po, Pmax], and the second adjustment step height is taken from the value range, for example, the value of the second adjustment step height is Po+1, and the second adjustment feathering height is obtained according to the second adjustment step height, wherein the second adjustment feathering height and the second adjustment step height satisfy the following formula:

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

[0075] Wherein, PRINTH is the printing height, PASSH' is the second adjustment step height, ECLPH' is the second adjustment feathering height, PASSMODE is the number of scans in the current printing mode, for example, the current printing mode is 2PASS printing, then PASSMODE is 2, and the following can be obtained:

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

[0077] The second adjustment step height and the printing height are known, and the second adjustment feathering height can be obtained according to the formula. According to the second adjustment step height and the second adjustment feathering height, the simulation printing can be performed, the printing position corresponding to the joint of the nozzle group in the next scanning printing is determined, that is, the third joint, if the third joint does not overlap with the first joint, the second adjustment step height at this time is recorded as the updated step height, if the third joint overlaps with the first joint (partially overlaps or completely overlaps), it means that the second adjustment step height and the second adjustment feathering height do not meet the requirements, then the value of the second adjustment step height is re-obtained from the above value range, for example, the value of the second adjustment step height is adjusted to Po+2, and then the corresponding second adjustment feathering height is obtained according to the adjusted second adjustment step height, and the position of the third joint is obtained by simulation printing……The above process is repeated until the third joint and the first joint do not overlap, and then the second adjustment step height and the second adjustment feathering height at this time are recorded as the updated step height and the updated feathering height. In actual application, the value step of the second adjustment step height can be adjusted in real time according to the simulation printing, and is not limited to the value step of 1 in the embodiment. In other embodiments, the best adjustment step of the step height can also be calculated according to the position of the third joint after the simulation printing according to the second adjustment step height and the second adjustment feathering height, and the updated step height is directly obtained according to the adjustment step, so as to reduce the loop process and improve the printing efficiency. After the updated feathering height and the updated step height are obtained, as shown in FIG. 8, the printing position corresponding to the joint of the nozzle group in the next scanning printing is not overlapped with the printing position corresponding to the joint of the nozzle group in the last scanning printing by adjusting the feathering height and the step height. Figure 6

[0078] It is worth pointing out that, when the next scanning printing is performed, the printing data corresponding to the next scanning printing needs to be processed according to the updated step height and the updated feathering height, for example, the position and height of the next scanning printing data in the entire printing data of the image to be printed are obtained according to the updated step height, the corresponding printing data is extracted and processed according to the updated feathering height, and then the feathering processed printing data is sent to the nozzle row in the nozzle group for printing.

[0079] ​In summary, the printing method for eliminating the overlapping splicing path provided by the embodiment of the present application comprises: obtaining a printing height, an original feathering height and an original stepping height; obtaining a printing area corresponding to a splicing position of a nozzle group during current scanning printing according to the original feathering height and the original stepping height, and recording the printing area as a first splicing path; adjusting the original feathering height and the original stepping height according to the printing height and the position of the first splicing path, and obtaining an updated feathering height and an updated stepping height; and controlling the nozzle group to perform next scanning 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 printing according to the updated feathering height and the updated stepping height does not overlap with the first splicing path.
