Description

Technical Field

[0001] This invention relates to the field of printing technology, and in particular to a printing method, apparatus, device, and storage medium for intelligently removing white border data during printing. Background Technology

[0002] Inkjet printers use nozzles to atomize colored liquid ink into tiny particles, which are then sprayed onto printing paper to create text or images. Existing inkjet printers use two main printing methods: interlaced printing and residence printing. In interlaced printing, the printhead advances a certain distance relative to the printing medium after each section is printed. In residence printing, the printhead only advances the distance of one printhead pass after each area has been printed; a single area may be printed in one pass or may require multiple passes.

[0003] In existing technologies, PCB boards typically employ a dwell-type printing method. During the printing process on some PCB boards, Gerber files may contain wide blank areas (also known as white borders). In such cases, direct printing causes the printhead to print outside the printing platform, and the reflected UV light can damage the printhead and ink stack. Furthermore, white borders in the Y direction increase the number of printing passes; what could be completed in 2 passes now requires 3, impacting printing efficiency. Summary of the Invention

[0041] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the invention.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0043] Example 1

[0044] Please see Figure 1 Embodiment 1 of the present invention provides a printing method for intelligently removing white border data, wherein: as Figure 1 As shown, the method includes the following steps:

[0045] S101. Obtain the size of the image to be printed and the white border data in the image to be printed;

[0046] For example, blank data can be parsed from the Gerber file of the image to be printed; this blank data represents the white border data in the image to be printed. The size of the image to be printed can be the size of the printing medium (e.g., a PCB board), which can be obtained through user input.

[0047] S102. Obtain printing data with white border data removed based on the size of the image to be printed and the white border data;

[0048] Wherein: the printing data ensures that the two printheads at both ends of the printhead layout will not be exposed outside the printing platform due to white edge data; for example, this step may include:

[0049] S11. Obtain the Y offset value and X offset value based on the white border data;

[0050] The Y offset value refers to the length of the white edge data in the Y direction of the image to be printed, and the X offset value refers to the length of the white edge data in the X direction of the image to be printed.

[0051] To facilitate subsequent printhead control, the Y-offset value includes: a first Y-offset value and a second Y-offset value. Obtaining the Y-offset value based on the white edge data includes: using the length of the white edge data in the Y direction corresponding to the first block as the first Y-offset value; and using the length of the white edge data in the Y direction corresponding to the last block as the second Y-offset value. Wherein: the Y direction is the direction of movement of the printhead or printing medium, the X direction is the direction of printhead scanning, and the Y and X directions are perpendicular. Wherein: the block represents the height of a unit area of ​​the image to be printed. A unit area of ​​the image to be printed can be completed in one pass or multiple passes. The number of passes for each unit area can be the same or different. For example, if the image to be printed is a character image on a PCB board, the number of passes for each unit area is the same because only one type of graphic needs to be printed. If the image to be printed is the entire PCB board image (including characters, color blocks, and lines), the number of passes for each unit area is different because characters, color blocks, and lines require different precision. When the unit area only contains color blocks, the number of passes can be reduced.

[0052] for example Figure 2a In 2b, the image to be printed includes the letter A and white borders on the top and bottom. The white border data in the first block corresponds to the length in the Y direction, which is the first printing Y offset Y1, corresponding to the length of the bottom white border of the image to be printed. The white border data in the last block corresponds to the length in the Y direction, which is the second printing Y offset Y2, corresponding to the length of the top white border of the image to be printed.

[0053] In other embodiments, only a portion of the white edge data may be removed, meaning the white edge data is not completely removed, retaining the blank data adjacent to the ink output data. The length of the blank data to be retained in the Y direction is obtained, and the lengths of the blank data to be retained on both sides of the image are denoted as the first retention length and the second retention length. In this case, obtaining the Y offset value based on the white edge data includes: subtracting the first retention length from the Y-direction length of the white edge data in the first block to obtain the first Y offset value; and subtracting the second retention length from the Y-direction length of the white edge data in the last block to obtain the second Y offset value. Furthermore, the portion of white edge data to be retained can be determined according to the actual situation. For example, if an interval region needs to be set between two adjacent images to be printed, the first retention length and the second retention length can be determined based on the size of the interval region as needed. When setting the first Y offset value and / or the second Y offset value, the first retention length and / or the second retention length are subtracted accordingly.

[0054] S12. Based on the size of the image to be printed, the Y offset value, and the X offset value, remove the white edge data at the beginning and end of the Y and X directions of the image to be printed to obtain the printing data;

[0055] For example, the Y offset values ​​at the beginning and end of the image to be printed can be removed in the Y direction, and the X offset values ​​at the beginning and end of the image to be printed can be removed in the X direction to obtain the printing data.

[0056] S103. Control the printhead to print according to the print data.

[0057] For example, this step may include:

[0058] S31. Calculate the actual number of printed blocks based on the print data;

[0059] One of them is an image length that can print a set of printhead heights, and a set of printheads includes at least one printhead. For example... Figure 2a In the original printing data of the image to be printed, there are 8 blocks to complete the printing. However, according to the present invention, after removing the white border data, only 5 blocks are needed to complete the printing. Obviously, the present invention can save the number of passes and improve printing efficiency.

[0060] S32. Obtain the overlapping block position and overlapping nozzle based on the Y offset value and the actual number of printed blocks;

[0061] In this invention, the actual number of blocks after removing white border data is not an integer number of Paas. At least two blocks in the actual printed blocks will overlap. The overlapping block position refers to the location where at least two blocks in the actual printed blocks overlap due to the removal of white border data.

[0062] In one example, the overlapping block position is located at the last block, and obtaining the overlapping block position and overlapping nozzle based on the Y offset value and the actual number of printed blocks includes: calculating the overlapping block position of the last block based on the Y offset value and the actual number of printed blocks; and determining the overlapping nozzle that does not dispense ink corresponding to the last block based on the overlapping block position.

[0063] Where: the Y offset value includes: the first Y offset value Y1 and the second Y offset value Y2, then the length L of the overlapping block position is L = J1 - (Y - Y1 - Y2 - (n-1)J1), where: J1 is the nozzle group height, Y is the length of the image to be printed (including white edges) in the Y direction, n is the actual number of printed blocks, and the overlapping block position can be determined based on the corresponding position of the last block and the length L of the overlapping block position. For example Figure 2a In this embodiment, the length L of the overlapping block position is calculated as J1 - (Y - Y1 - Y2 - 4J1). The overlapping block position can be determined based on the starting coordinate of the last block in the Y direction, the length L of the overlapping block position, and the positional relationship between the overlapping block position and the last block. In this embodiment, the overlapping block position is located at the bottom of the last block. Subsequently, based on the relationship between the number of blocks and the printhead, the overlapping block position is converted into the corresponding overlapping printhead, thereby determining the overlapping nozzle that does not produce ink corresponding to the last block.

[0064] In another example, the overlapping block positions are located at the first and last blocks, and obtaining the overlapping block positions and overlapping nozzles based on the Y offset value and the actual number of printed blocks includes: determining the overlapping block positions of the first block and the last block respectively based on the Y offset value;

[0065] The overlapping nozzles that do not produce ink are determined based on the position of the first overlapping block, and the overlapping nozzles that do not produce ink are determined based on the position of the last overlapping block.

[0066] Wherein: the Y offset value includes: a first Y offset value Y1 and a second Y offset value Y2. The length L1 of the overlapping block position of the first block is Y1. The overlapping block position of the first block can be determined based on the corresponding position of the first block and the length L1 of the overlapping block position. Subsequently, according to the relationship between the number of blocks and the printhead, the overlapping block position of the first block is converted into the corresponding overlapping printhead, thereby determining the overlapping nozzle that does not produce ink corresponding to the first block. The length L2 of the overlapping block position of the last block is Y2. The overlapping block position of the last block can be determined based on the corresponding position of the last block and the length L2 of the overlapping block position. Subsequently, according to the relationship between the number of blocks and the printhead, the overlapping block position of the last block is converted into the corresponding overlapping printhead, thereby determining the overlapping nozzle that does not produce ink corresponding to the last block. For example... Figure 2bThe length L1 of the overlapping block position of the first block is Y1. The position of the overlapping block of the first block can be determined based on the starting coordinate of the first block in the Y direction, the length L1 of the overlapping block position, and the positional relationship between the overlapping block position and the first block. In this embodiment, the overlapping block position of the first block is located at the top of the first block. Subsequently, according to the relationship between the number of blocks and the printhead, the overlapping block position of the first block is converted into the corresponding overlapping printhead, thereby determining the overlapping nozzle that does not produce ink corresponding to the first block. The length L2 of the overlapping block position of the last block is Y2. The position of the overlapping block of the last block can be determined based on the starting coordinate of the last block in the Y direction, the length L2 of the overlapping block position, and the positional relationship between the overlapping block position and the last block. In this embodiment, the overlapping block position of the last block is located at the bottom of the last block. Subsequently, according to the relationship between the number of blocks and the printhead, the overlapping block position of the last block is converted into the corresponding overlapping printhead, thereby determining the overlapping nozzle that does not produce ink corresponding to the last block.

[0067] It is worth noting that the position of the overlapping block is not limited to the first or last block. In other embodiments, the printing system can intelligently set the optimal position of the overlapping block based on the Y offset value, the actual number of printed blocks, and the height of the printhead assembly. For example, the overlapping block can be set in any block, or each block can have an overlapping block, thereby making the entire printing process more efficient and the data processing speed faster.

[0068] S33. Control the inkjet nozzle to spray ink according to the actual number of printed blocks, and close the overlapping nozzle when the ink is sprayed to the position of the overlapping block.

[0069] For example, print data is input into the print channel of the corresponding block to control the printhead to print, and the overlapping nozzle is turned off when ink is sprayed to the position of the overlapping block.

[0070] Example 2

[0071] Embodiment 2 of the present invention provides a printing method for intelligently removing white border data. The difference between this method and Embodiment 1 is that, before obtaining the size of the image to be printed and the white border data in the image to be printed, the method further includes:

[0072] S1. Determine if there is white border data in the image to be printed;

[0073] For example, the Gerber file of the image to be printed can be parsed to determine whether there is blank data in the file. If blank data exists, then there is white border data in the image to be printed.

[0074] To avoid mistaking inherent blank areas in an image for white border data, coordinate conditions can be pre-set. The system checks if data satisfying these conditions is indeed white border data. If the data satisfying these conditions is blank, then white border data exists in the image to be printed. These coordinate conditions can be the coordinates of the top, bottom, left, or right edge of the image to be printed. In other words, the presence of white border data in the image to be printed is determined by checking for blank data at its top, bottom, left, or right edge regions.

[0075] S2. If the image to be printed contains white border data, enable the white border printing mode.

[0076] In this embodiment, after enabling the white border printing mode, the process proceeds to step S101 in Embodiment 1.

[0079] The acquisition module 31 is used to acquire the size of the image to be printed and the white border data in the image to be printed;

[0080] The removal module 32 is used to obtain print data with white edge data removed based on the size of the image to be printed and the white edge data; the print data ensures that the two printheads at both ends of the printhead layout will not be exposed outside the printing platform due to the white edge data.

[0081] The control module 33 is used to control the printhead to print according to the print data.

[0082] In one specific embodiment, the removal module 32 includes:

[0083] The first acquisition module is used to obtain the Y offset value and X offset value based on the white border data;

[0084] The second acquisition module is used to obtain printing data by removing the white edge data at the beginning and end of the Y and X directions of the image to be printed based on the size of the image to be printed, the Y offset value, and the X offset value.

[0087] The calculation module is used to calculate the actual number of printed blocks based on the print data;

[0088] The second acquisition module is used to obtain the overlapping block position and overlapping nozzle based on the Y offset value and the actual number of printed blocks;

[0089] The sub-control module is used to control the inkjet nozzle to spray ink according to the actual number of printed blocks, and to close the overlapping nozzle when ink is sprayed to the position of the overlapping block.

[0090] In one example, the overlapping block is located at the last block, and the second acquisition module includes:

[0091] The sub-calculation module is used to calculate the position of the overlapping block of the last block based on the Y offset value and the actual number of printed blocks;

[0092] The first determining module is used to determine the overlapping nozzle that does not produce ink, corresponding to the last overlapping block, based on the position of the overlapping block.

[0093] In another example, the overlapping block positions are located between the first and last blocks, and the second acquisition module includes:

[0094] The second determining module is used to determine the overlapping block position of the first block and the overlapping block position of the last block based on the Y offset value.

[0095] The third determining module is used to determine the non-inking overlapping nozzle corresponding to the first block based on the position of the overlapping block of the first block, and to determine the non-inking overlapping nozzle corresponding to the last block based on the position of the overlapping block of the last block.

[0096] In one embodiment, the Y offset value includes: a first Y offset value and a second Y offset value. The first acquisition module takes the length of the white edge data in the Y direction corresponding to the first block as the first Y offset value and takes the length of the white edge data in the Y direction corresponding to the last block as the second Y offset value.

[0097] Furthermore, the device also includes:

[0098] The judgment module is used to determine whether there is white border data in the image to be printed;

[0099] The module enables white-border printing mode if the image to be printed contains white-border data.
