Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.
Example 1
Referring to fig. 1, a first embodiment of the present invention provides a printing method for intelligently removing white edge data, wherein: as shown in fig. 1, the method comprises the steps of:
s101, acquiring the size of an image to be printed and white edge data in the image to be printed;
for example, the blank data may be parsed from the Gerber file of the image to be printed, and the blank data is the white edge data in the image to be printed. The size of the image to be printed may be the size of the print medium (e.g., a PCB board) and may be obtained by user input.
S102, obtaining the printing data from which the white edge data is removed according to the size of the image to be printed and the white edge data;
wherein: the printing data ensures that two nozzles at two ends in the nozzle layout are not exposed outside the printing platform due to white edge data; illustratively, this step may include:
s11, acquiring a Y offset value and an X offset value according to white edge data;
wherein, the Y offset value refers to the length value of the white edge data corresponding to the Y direction of the image to be printed, and the X offset value refers to the length value of the white edge data corresponding to the X direction of the image to be printed.
For the convenience of the subsequent control of the spray head, the Y offset value comprises: the first Y offset value and the second Y offset value, the obtaining the Y offset value according to the white edge data includes: taking the length of the white edge data corresponding to the Y direction in the first block as a first Y offset value; and taking the length of the white edge data corresponding to the Y direction in the last block as a second Y offset value. Wherein: the Y direction is the direction in which the nozzle or the printing medium moves, the X direction is the direction in which the nozzle scans, and the Y direction is perpendicular to the X direction. The block is the height of the unit area of the image to be printed, the unit area of the image to be printed can be printed by 1pass or by multiple passes, the number of passes printed by each unit area can be the same or different, for example, the image to be printed is a character diagram in a PCB, at the moment, the number of passes printed by the unit area is the same, because only one pattern needs to be printed, for example, the image to be printed is the whole diagram (comprising characters, color blocks and circuits) of the PCB, at the moment, the number of passes printed by the unit area is different, because the precision required by the characters, the color blocks and the circuits is different, and the number of passes can be reduced when the unit area is only provided with the color blocks.
For example, in fig. 2a and 2b, the image to be printed includes a letter a and a white edge on the upper and lower sides, the length of the white edge data corresponding to the Y direction in the first block is the first printing Y offset Y1, the length of the white edge corresponding to the lower side of the image to be printed is the second printing Y offset Y2, and the length of the white edge data corresponding to the Y direction in the last block is the length of the white edge on the upper side of the image to be printed.
In other embodiments, only a portion of the white edge data may be removed, i.e., the white edge data is not completely removed, leaving a portion of the blank data adjacent to the ink-out data. The method for acquiring the length of the blank data to be reserved in the Y direction, respectively recording the reserved lengths of the blank data on two sides of the image to be blocked as a first reserved length and a second reserved length, wherein the step of acquiring the Y offset value according to the blank data comprises the following steps: subtracting the first reserved length from the corresponding Y-direction length of the white edge data in the first block to obtain a first Y offset value; the length of the white edge data in the last block corresponding to the Y direction is subtracted by the second reserved length to be used as a second Y offset value. In addition, the part of white edge data to be reserved can be determined according to practical situations, for example, a spacing area needs to be set between two adjacent images to be printed, the size of the spacing area can be set according to requirements to determine a first reserved length and a second reserved length, and the first reserved length and/or the second reserved length are correspondingly subtracted when the first Y offset value and/or the second Y offset value are set.
S12, removing the white edge data of the head and the tail of the Y direction and the X direction of the image to be printed according to the size, the Y offset value and the X offset value of the image to be printed to obtain printing data;
for example, the head-to-tail Y offset value may be removed in the Y direction of the image to be printed, and the head-to-tail X offset value may be removed in the X direction of the image to be printed, to obtain the print data.
And S103, controlling the nozzle to print according to the printing data.
Illustratively, this step may include:
s31, calculating the actual number of printing blocks according to the printing data;
wherein a block can print an image length of a set of head heights, a set of heads including at least one head. As shown in fig. 2a, the image to be printed includes letter a and the upper and lower edges, 8 blocks are required to complete printing according to the original print data of the image to be printed, and 5 blocks are required to complete printing according to the print data of the blank data removed according to the invention, obviously, the invention can save pass number and improve printing efficiency.
S32, acquiring overlapped block positions and overlapped nozzles according to the Y offset value and the actual printing block number;
in the invention, the actual number of blocks after the white edge data is removed is not the whole paas number, and an overlapping position exists between at least two blocks in the actual printing blocks. The overlapped block position refers to a position where at least two blocks in the actual printing block have overlap after the white edge data is removed.
In one example, the overlapped block position is located at the last block, and the acquiring the overlapped block position and the overlapped nozzle according to the Y offset value and the actual number of printing blocks includes: calculating the overlapped block position of the last block according to the Y offset value and the actual printing block number; and determining the overlapped nozzle which does not discharge ink and corresponds to the last block according to the position of the overlapped block.
Wherein: the Y offset value includes: first Y offset value Y1 and second Y offset value Y2, then the length of the overlapped block position l=j1- (Y-Y1-Y2- (n-1) J1), wherein: j1 is the height of the nozzle group, Y is the length of an image to be printed (including white edges) in the Y direction, n is the number of actual printing blocks, and the position of the overlapped block can be determined according to the corresponding position of the last block and the length L of the position of the overlapped block. For example, in fig. 2a, the length l=j1- (Y-Y1-Y2-4J 1) of the overlapped block position may be determined according to the start coordinate of the last block corresponding to the Y direction, the length L of the overlapped block position, and the positional relationship between the overlapped block position and the last block. In this embodiment, the overlapped block is located at the bottom of the last block. Subsequently, the overlapped block positions are converted into corresponding overlapped ejection heads according to the relationship between the number of blocks and the ejection heads, thereby determining the overlapped nozzles corresponding to the last block which do not discharge ink.
In another example, the overlapped block positions are located in a first block and a last block, and the acquiring the overlapped block positions and the overlapped nozzles according to the Y offset value and the actual number of printing blocks includes: respectively determining the overlapped block position of the first block and the overlapped block position of the last block according to the Y offset value;
and determining the overlapping nozzle which does not emit ink and corresponds to the first block according to the overlapping block position of the first block, and determining the overlapping nozzle which does not emit ink and corresponds to the last block according to the overlapping block position of the last block.
Wherein: the Y offset value includes: and if the first Y offset value Y1 and the second Y offset value Y2 are equal, determining the length l1=y1 of the overlapped block position of the first block according to the corresponding position of the first block and the length L1 of the overlapped block position, and then converting the overlapped block position of the first block into the corresponding overlapped nozzle according to the relation between the number of blocks and the nozzle, thereby determining the overlapped nozzle corresponding to the first block and not discharging ink. The length l2=y2 of the overlapped block position of the last block, the overlapped block position of the last block may be determined according to the corresponding position of the last block and the length L2 of the overlapped block position, and then, according to the relationship between the number of blocks and the head, the overlapped block position of the last block is converted into the corresponding overlapped head, thereby determining the overlapped nozzle corresponding to the last block which does not discharge ink. As shown in fig. 2b, the length l1=y1 of the overlapped block position of the first block may be determined according to the start coordinate of the first block corresponding to the Y direction, the length L1 of the overlapped block position of the first block, and the positional relationship between the overlapped block position of the first block and the first block. In this embodiment, the overlapping block position of the first block is located on top of the first block. Subsequently, according to the relationship between the number of blocks and the ejection heads, the overlapping block position of the first block is converted into a corresponding overlapping ejection head by the first block, thereby determining the overlapping nozzles corresponding to the first block that do not discharge ink. The length l2=y2 of the overlapped block position of the last block, the overlapped block position of the last block may be determined according to the start coordinate of the last block corresponding to the Y direction, the length L2 of the overlapped block position of the last block, and the positional relationship between the overlapped block position of the last block and the last block. In this embodiment, the overlapped block position of the last block is located at the bottom of the last block. Then, according to the relation between the number of blocks and the nozzles, the overlapping block position of the last block is converted into the corresponding overlapping nozzle by the last block, so that the overlapping nozzle which does not discharge ink and corresponds to the last block is determined.
It should be noted that the position of the overlapped block is not limited to the first block or the last block, and in other embodiments, the optimal position of the overlapped block may be intelligently set by the printing system according to the Y offset value and the actual number of printed blocks and the height of the nozzle group, for example, the overlapped block is set in any block, or each block is provided with the overlapped block, so that the whole printing process is more efficient and the data processing speed is faster.
S33, ink is ejected from the nozzle according to the actual printing block number, and the overlapping nozzles are closed when the ink is ejected to the overlapping block positions.
Illustratively, print data is input into the print channels of the corresponding blocks to control the nozzles to print, and the overlapping nozzles are closed when ink is ejected to the overlapping block positions.
