Oneepass printing has the advantages of high efficiency and large output, and is suitable for large-batch and continuous printing. In order to print various image data from a plurality of image storage devices on printing paper, the Onepass printing needs to merge data in a channel in the data processing process, and needs to take out the existing data in a data cache to operate with new data and write the data in the cache again.

Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
Example 1:
the object of example 1 of the present invention is to print an image as shown in figure 1, i.e. image a and image B, both independent images, on the same substrate. In this embodiment 1, image a is background image data and image B is label image data (i.e., image a is a constant background and image B is a specific label, while printing image a and image B is printing a label image on one side of the background image, the label being, for example, a number "1122445669" representing a product model, and the label image being changeable).
In embodiment 1 of the present invention, the number of nozzles (one nozzle corresponds to one printing channel) of the Onepass printing apparatus is 7, the starting points of all the printing channels are positions with coordinates (0,0) in fig. 1, the 7 nozzles are sequentially arranged along the X-axis direction, and the printing medium moves in the Y-axis direction during the Onepass printing process. The 7 spray heads are a first spray head P1, a second spray head P2, a third spray head P3, a fourth spray head P4, a fifth spray head P5, a sixth spray head P6 and a seventh spray head P7 in sequence from left to right, and 100 spray nozzles (one spray nozzle corresponds to one pixel) are arranged in one spray head.
When the printing system prints the image a individually, a data buffer is provided in the printing system for each head, data in the head corresponding to the data buffer is stored in each data buffer, 7 data buffers are buff01, buff02, buff03, buff04, buff05, buff06, and buff07(buff01, buff02, buff03, buff04, buff05, buff06, and buff07 correspond to the first head P1, the second head P2, the third head P3, the fourth head P4, the fifth head P5, the sixth head P6, and the seventh head P7, respectively), and the 7 data buffers can be accessed at the same time. In this embodiment, each data cache is a dual-port data cache (although a single-port data cache may be used as the data cache, the type of the data cache is not limited here), as shown in fig. 4, the first address of buff01 is addrA01, the data in the first address is idata 01, the second address of buff01 is addrB01, the data in the second address is odab 01, and the structure of the remaining data caches is similar to that of the data cache buff 01.
As shown in fig. 2, the width of the image a along the nozzle arrangement direction is 290 pixels, and the initial printing position of the image a is the 30 th pixel position of the third nozzle. Establishing a printing coordinate system with pixels as basic units, setting the coordinates of the starting points of all printing channels as (0,0), and when the coordinate value of the Y axis is 350, the coordinate value of the initial printing image of the image A on the X axis in the printing coordinate system is 230 and the coordinate value of the ending printing image is 520, and the printing range of the image on the X axis at the moment is 230 to 520. From this, it is understood that the print data corresponding to each nozzle stored in buff01, buff02, and buff07 is "0", and the print data corresponding to each nozzle stored in buff04 and buff05 is "1"; the print data corresponding to the first 30 nozzles stored in buff03 is "0", and the print data corresponding to the last 70 nozzles stored in buff03 is "1"; the print data corresponding to the first 30 nozzles stored in buff06 is "1", and the print data corresponding to the last 70 nozzles stored in buff06 is "0". (buff01, buff02, buff03, buff04, buff05, buff06 and buff07 are data buffers for each head when image A is printed individually)
When the printing system prints the image B separately, a data buffer is provided in the printing system for each head, data in the head corresponding to the data buffer is stored in each data buffer, 7 data buffers are respectively buf 01 ', buf 02 ', buf 03 ', buf 04 ', buf 05 ', buf 06 ' and buf 07 ' (buf 01 ', buf 02 ', buf 03 ', buf 04 ', buf 05 ', buf 06 ', and buf 07 ' are respectively in one-to-one correspondence with the first head P1, the second head P2, the third head P3, the fourth head P4, the fifth head P5, the sixth head P6, and the seventh head P7), and the data stored in the buf 01 ', buf 02 ', buf 03 ', buf 04 ', buf 05 ', buf 06 ', and the buf 07 ' and the data to be written in the data buffers, and the data buffers 7 data can be accessed simultaneously. Each data cache is a dual-port data cache (of course, a single-port data cache may also be used for the data cache, and the type of the data cache is not limited here). As shown in fig. 5, the first address of buff01 ' is addrA01 ', the data in the first address is iDataA01 ', the second address of buff01 ' is addrB01 ', the data in the second address is odab 01 ', and the structure of the rest of the data cache is similar to that of data cache buf 01 '.
As shown in fig. 3, the width of the image B along the nozzle arrangement direction is 110 pixels, and the initial printing position of the image B is the 50 th pixel position of the first nozzle. When the Y-axis coordinate value is 350, the start print image coordinate value of the image B on the X-axis in the print coordinate system is 50 and the end print image coordinate value is 160, and the print range of the image on the X-axis at this time is 50 to 160. From this, it is understood that the print data corresponding to each nozzle stored in buff03 ', buff04 ', buff05 ', buff06 ' and buff07 ' is "0", the print data corresponding to the first 50 nozzles stored in buff01 ' is "0", and the print data corresponding to the last 50 nozzles stored in buff01 ' is "1"; the print data corresponding to the first 60 nozzles stored in buf 02 ' is "1", and the print data corresponding to the last 40 nozzles stored in buf 02 ' is "0" (buf 01 ', buf 02 ', buf 03 ', buf 04 ', buf 05 ', buf 06 ', and buf 07 ' are data buffers of the heads when the image B is printed individually).
In order to print the image a and the image B on the same printing stock as shown in fig. 3, the data cached in the corresponding nozzles in the image a and the image B are processed and then read into the nozzles. The method for efficiently processing Oneepass printing data in the embodiment 1 of the invention specifically comprises the following steps (taking the first spray head as an example):
s1, setting a data buffer buf 11(buff11 corresponds to the second data buffer) with the same structure as the data buffer buf 01(buff01 corresponds to the first data buffer), as shown in fig. 6, the first address of buff11 is addrA11, the data in the first address is idata 11, the second address of buff11 is addrB11, and the data in the second address is odab 11;
s2, connecting the first address addrA11 of buff11 to the second address addrB01 of buff01, the first address addrA11 of buff11 obtaining the first print data in the second address addrB01 of buff01 (this step has a clock delay); at this time, the data stored in the data buffer buf 11 and the data stored in buf 01 are both the first print data (i.e., buf 11 serves as the shadow buffer of buf 01);
s3, an operation result (a clock delay in this step) obtained by logically or-ing data odab 11 (first print data) in second address addrB11 of buff11 and data odab 01 ' (second print data) in second address addrB01 ' of buff01 ';
for example, when the Y-axis coordinate value is 350, the print data value obtained by or-ing the 55 th nozzle print data (value "1") stored in buff11 and the 55 th nozzle print data (value "0") stored in buff 01' is "1".
S4, storing the operation result obtained in the step S3 into the first address addrA01 of buff01 and the first address addrA11 of buff11 respectively (the step has a clock delay);
s5, reads the data of idata b01 from the second address addrB01 of buff01 as print data and inputs the print data to the first head to eject ink.
As shown in the above steps S1 to S5, the print data is processed by a double-buffer (two data buffers) pipeline to complete the operations of fetching the target address from the buffer, and writing the target address into the buffer after completing the calculation in one clock cycle; the data processing period is matched with the system printing period, so that the nozzle can receive the next printing data without waiting, and the printing efficiency is improved.
The data processing process of the other nozzles is the same as that of the first nozzle, namely, the data in buf 01 and buf 01 ' are subjected to OR operation, the data in buf 02 and buf 02 ' are subjected to OR operation, the data in buf 03 and buf 03 ' are subjected to OR operation, the data in buf 04 and buf 04 ' are subjected to OR operation, the data in buf 05 and buf 05 ' are subjected to OR operation, the data in buf 06 and buf 06 ' are subjected to OR operation, and the data in buf 07 and buf 07 ' are subjected to OR operation.
The multi-pass merge is to merge (logically operate) data of a plurality of passes at the time of individually printing the image A, B, thereby forming print data of a print target.
Example 2:
the efficient processing method of Oneepass printing data in the embodiment 2 of the invention is improved on the basis of the efficient processing method of Oneepass printing data in the embodiment 1. Specifically, the method for efficiently processing Onepass printing data in embodiment 2 specifically includes the following steps:
s1, setting a data buffer buf 11(buff11 corresponds to the second data buffer) with the same structure as the data buffer buf 01(buff01 corresponds to the first data buffer), as shown in fig. 6, the first address of buff11 is addrA11, the data in the first address is idata 11, the second address of buff11 is addrB11, and the data in the second address is odab 11;
s2, connecting the first address addrA11 of buff11 to the second address addrB01 of buff01, the first address addrA11 of buff11 obtaining the first print data in the second address addrB01 of buff01 (this step has a clock delay); at this time, the data stored in the data buffer buf 11 and the data stored in buf 01 are both the first print data (i.e., buf 11 serves as the shadow buffer of buf 01);
s3, an operation result (a clock delay in this step) obtained by logically or-ing data odab 11 (first print data) in second address addrB11 of buff11 and data odab 01 ' (second print data) in second address addrB01 ' of buff01 ';
for example, when the Y-axis coordinate value is 350, the print data value obtained by or-ing the 55 th nozzle print data (value "1") stored in buff11 and the 55 th nozzle print data (value "0") stored in buff 01' is "1".
S4, storing the operation result obtained in the step S3 into the first address addrA01 of buff01 and the first address addrA11 of buff11 respectively (the step has a clock delay);
s5, reading the data of the idadatab 01 from the second address addrB01 of the buf 01 as printing data, and inputting the printing data to the first head for ink jetting (after the ink jetting is completed this time, the first head jets and prints a horizontal row of ink with the Y-axis coordinate value of 350).
S6, the data buffer buff01 receives the next first print data (the Y-axis coordinate value in fig. a is the 351-th first print data), and the data buffer buff 01' receives the next second print data (the Y-axis coordinate value in fig. B is the 351-th first print data). The first address addrA11 of buff11 acquires the next first print data in the second address addrB01 of buff01 (this step has a clock delay); at this time, the data stored in the data buffer buf 11 and the data stored in buf 01 are both the next first print data;
s7, an operation result (a clock delay in this step) obtained by logically or-ing data odab 11 (next first print data) in second address addrB11 of buff11 and data odab 01 ' (next second print data) in second address addrB01 ' of buff01 ';
for example, when the Y-axis coordinate value is 351, the print data value obtained by or-ing the 55 th nozzle print data (value "1") stored in buff11 and the 55 th nozzle print data (value "0") stored in buff 01' is "1".
S8, storing the operation result obtained in the step S7 into the first address addrA01 of buff01 and the first address addrA11 of buff11 respectively (the step has a clock delay);
s9, outputting and printing the result of the logic operation stored in the data buffer buff 01;
and S10, repeating the steps S6 to S9 until all the first printing data printed by Oneepass are processed (the values of the first printing data are different according to the Y coordinate). After step S10 is completed, the image shown in fig. 1 is printed.
Example 3:
as shown in fig. 7, the image to be printed in embodiment 3 of the present invention is the image a added with the image C on the right side thereof on the basis of the image to be printed in embodiment 1. In this embodiment 3, the image a is background image data, the image B is first label image data, and the image C is second label data (i.e., the image a is a constant background, the image B is a specific label, and the image C is also a specific label).
When the printing system prints the image C individually, a data buffer is provided in the printing system for each head, data in the head corresponding to the data buffer is stored in each data buffer, 7 data buffers are buff01 ", buff 02", buff03 ", buff 04", buff05 ", buff 06", and buff07 "(buff 01", buff02 ", buff 03", buff04 ", buff 05", buff06 ", and buff 07" are in one-to-one correspondence with the first head P1, the second head P2, the third head P3, the fourth head P4, the fifth head P5, the sixth head P6, and the seventh head P7), respectively, and the 7 data buffers can be accessed at the same time. Each data cache is a dual-port data cache. The first address of buff01 ' is addrA01 ', the data in the first address is iDataA01 ', the second address of buff01 ' is addrB01 ', the data in the second address is oDataB01 ', and the structure of the rest of the data cache is similar to that of data cache buf 01 '.
The width of the image C along the nozzle arrangement direction is 100 pixels, and the initial printing position of the image C is the position of the 70 th pixel point of the sixth nozzle (the 70 th pixel point counted from left to right). When the Y-axis coordinate value is 350, the start print image coordinate value of the image C on the X-axis in the print coordinate system is 570 and the end print image coordinate value 670, and the print range of the image on the X-axis at this time is 570 to 670.
