If not conflicting, the embodiments of the present application and the features of the embodiments may be combined with each other, which are all within the protection scope of the present application.
Example 1:
the embodiment discloses a method for printing Onepass insertion points, as shown in fig. 1, the nozzle module for printing is formed by splicing a plurality of nozzles, and at least two rows of adjacent nozzles of the nozzle module are staggered along the direction of the nozzle row. Referring to fig. 2, the distribution of ink dots for oneplass printing using the aforementioned head module structure may be more dense. As shown in fig. 4, the method comprises the steps of:
s1: acquiring splicing positions and splicing nozzle rows of two adjacent splicing spray heads;
in this step, the number of rows and the splicing position of the spliced nozzles can be obtained from the nozzle parameters, for example, in fig. 1, the nozzle P1 and the nozzle P2 are spliced nozzles, the tail of the nozzle P1 and the head of the nozzle P2 are spliced to form a nozzle module, and the row A1, the row A2, the row A3 and the row B1, the row B2 and the row B3 of the nozzle P2 are spliced to form 3 rows of spliced nozzles, so that the number of rows of spliced nozzles is 3 rows, and the splicing position is the position of the tail of the row A1, the row A2, the position of the tail of the row A3 and the position of the head of the row B1, the row B2 and the row B3 of the nozzle P2. In this embodiment, the number of the splicing nozzles may be 2 or greater than or equal to 2.
In addition, the number of the spliced nozzle rows and the spliced positions can be obtained in a test printing mode.
S2: determining nozzle closing information corresponding to each row of splicing nozzles according to the printing parameters, the splicing positions and the splicing nozzle rows, wherein the nozzle closing information comprises nozzle closing positions and nozzle closing numbers;
the printing parameters include the number of insertion points, and when the number of insertion points is larger, the ink points ejected onto the printing medium by the nozzles are denser, so that the splicing channel is easier to form. The number of the spliced nozzle rows and the spliced position can be combined through the printing parameters to determine the nozzle closing information corresponding to each row of spliced nozzles. The nozzle closing information includes the position of the nozzle to be closed in the row of nozzles, that is, the nozzle closing position information, and the number of the nozzles to be closed in the row of nozzles, that is, the nozzle closing number information.
S3: and controlling corresponding nozzles in each row of spliced nozzles to not generate ink in the ink-jet printing process according to the nozzle closing information corresponding to each row of spliced nozzles, and enabling the number of the nozzles which do not generate ink in at least two rows of spliced nozzles to be different.
After the closing information of each row of spliced nozzles is determined, the ink-jet state of each row of nozzles can be independently controlled in the printing process, so that a part of nozzles in each row of spliced nozzles cannot generate ink in the ink-jet printing, and the nozzles which cannot generate ink can be independently adjusted according to the number of the nozzles which cannot generate ink in each row of nozzles. As shown in fig. 5, the number of non-ink-ejecting nozzles corresponding to each row of the spliced nozzles may be set to be different from the number of non-ink-ejecting nozzles corresponding to at least two rows of spliced nozzles.
For example, a total of 4 rows of spliced nozzles are respectively a first row of nozzles L1, a first row of nozzles L2, a first row of nozzles L3 and a first row of nozzles L4, wherein the number of closed nozzles corresponding to the first row of nozzles L1 is 3, in this step, 3 nozzles in the first row of nozzles L1 are controlled to not generate ink in the inkjet printing process, the number of closed nozzles corresponding to the first row of nozzles L2 is 3, in this step, 2 nozzles in the first row of nozzles L2 are controlled to not generate ink in the inkjet printing process, the number of closed nozzles corresponding to the first row of nozzles L3 is 3, in this step, 2 nozzles in the first row of nozzles L1 are controlled to not generate ink in the inkjet printing process, and the number of closed nozzles corresponding to the first row of nozzles L4 is 4, in this step, 4 nozzles in the first row of nozzles L4 are controlled to not generate ink in the inkjet printing process.
As shown in fig. 6, the S2: determining nozzle closing information corresponding to each row of splicing nozzles according to printing parameters, the splicing positions and the splicing nozzle rows, wherein the nozzle closing information comprises nozzle closing positions and nozzle closing quantity, and the method comprises the following steps of:
s21: determining the closing quantity of the nozzles corresponding to each row of splicing nozzles according to the printing parameters, the splicing positions and the splicing nozzle rows;
the method comprises the steps of determining the closing quantity of the nozzles corresponding to each row of spliced nozzles, wherein the closing quantity of the nozzles meets the requirement that the quantity of the nozzles which are not used for discharging ink and corresponding to at least two rows of spliced nozzles in the inkjet printing process is different.
S22: and determining the position number of the nozzle to be closed in each row of nozzles according to the splicing position and the corresponding closing number of the nozzles in each row of nozzles.
As shown in fig. 7, in order to quickly and accurately determine the positions of the corresponding nozzles to be closed in each row of the spliced nozzles, the nozzles in each row may be numbered according to the positions. For example, the head P1 has 4 rows of splice nozzles, which are the 1 st row of nozzles M1, the 2 nd row of nozzles M2, the 3 rd row of nozzles M3, and the 4 th row of nozzles M4, respectively. Wherein, the nozzles in the 1 st row are provided with 9 nozzles, the nozzles are numbered sequentially from the head to the tail of the nozzles in the 1 st row, and the numbers are respectively 1, 2, 3 and 4 … …; the nozzles in the 2 nd row are provided with 8 nozzles, and the nozzles are numbered sequentially from the head to the tail of the nozzles in the 2 nd row, and the numbers are respectively 1, 2, 3 and 4 … …; the nozzles in the 3 rd row are provided with 9 nozzles, and the nozzles are numbered sequentially from the head to the tail of the nozzle in the 3 rd row, and the numbers are respectively 1, 2, 3 and 4 … …; the nozzles in the 4 th row are all 10 nozzles, and the nozzles are numbered sequentially from the head to the tail of the nozzles in the 4 th row, and the numbers are respectively 1, 2, 3 and 4 … …. The number of nozzles in each row may be the same or different. When the number of nozzles corresponding to each row of the splicing nozzles is determined, the nozzles meeting the number of the closed nozzles of the front-nozzle attachment at the splicing position can be selected from each row of the splicing nozzles as the nozzles which do not emit ink in the printing process. Since the above numbers indicate the positional relationship between the nozzles, the positions of these ink-non-discharging nozzles can be indicated by the above numbers, and for example, 3 nozzles having the position numbers 7, 8, and 9 in the 1 st row of nozzles L1 are selected as the nozzles that do not discharge ink during printing, and 3 consecutive nozzles having the position of the 1 st column of tail of the head P1 are selected as the nozzles that do not discharge ink.
According to the Onepass insertion point printing method, the nozzle closing positions and the nozzle closing numbers of the splicing nozzles in each row are independently set according to printing parameters, the splicing positions and the splicing nozzle rows, the numbers of the nozzles which do not emit ink in at least two rows of the splicing nozzles are different, and then the corresponding nozzles in each row of the splicing nozzles are processed according to the nozzle closing information corresponding to each row of the splicing nozzles, so that the corresponding nozzles do not emit ink in the ink-jet printing process. The number of the nozzles which do not emit ink in at least two rows of splicing nozzles is different, so that the situation that the splicing channels are changed from black channels to white due to the influence of external factors in actual printing caused by the fact that the closing hole numbers of all the splicing nozzles are consistent is avoided, and the processed printing image is more uniform at the splicing position of the spray head.
As a preferred embodiment, the present embodiment is as follows in S21: and determining the closing quantity of the nozzles corresponding to each row of splicing nozzles according to the printing parameters, the splicing positions and the splicing nozzle rows so that the closing quantity of the nozzles corresponding to any two adjacent rows of splicing nozzles is different.
After the method is adopted, the closing numbers of the nozzles corresponding to any two adjacent rows of splicing nozzles are different, so that the closing numbers of the nozzles corresponding to each row of splicing nozzles and the splicing nozzles at two adjacent sides are different, and the obvious condition that a black channel becomes white can not occur during printing.
As a preferred embodiment, in S22: and determining the positions of the nozzles to be closed of two adjacent rows of splicing nozzles in each row of nozzles according to the splicing positions and the closing quantity of the nozzles corresponding to each row of nozzles.
For example, there are a total of 4 rows of splice nozzles, namely, a first row of nozzles L1, a first row of nozzles L2, a first row of nozzles L3, and a first row of nozzles L4, each row of nozzles having 10 nozzles, numbered sequentially from 1 to 10 in position. The number of nozzles to be closed in the first row of nozzles L1 may be set to 2, and the positions of the nozzles to be closed are numbered 6 and 7; the number of nozzles to be closed in the second row of nozzles L2 is 3, and the positions of the nozzles to be closed are numbered 5, 6 and 7; the number of nozzles to be closed in the third row of nozzles L3 is 2, and the positions of the nozzles to be closed are numbered 6 and 7; the number of nozzles to be closed in the fourth row of nozzles L4 is 3, and the positions of the nozzles to be closed are numbered 5, 6, and 7.
By adopting the mode that the adjacent two rows of closing nozzles are staggered, the closing quantity of the nozzles corresponding to any two adjacent rows of splicing nozzles can be ensured to be different, and the non-uniformity formed at the splicing position can be eliminated more thoroughly.
As shown in fig. 8, in the present embodiment, the step S21: determining the closing quantity of the nozzles corresponding to each row of splicing nozzles according to the printing parameters, the splicing positions and the row of splicing nozzle columns, wherein the method comprises the following steps:
s211: determining a first initial closing quantity corresponding to each row of nozzles according to the printing parameters, the splicing positions and the splicing nozzle columns;

S214: and adjusting the first initial closing quantity of each row of splicing nozzles row by row according to the first closing quantity and the second closing quantity to obtain the closing quantity of the nozzles corresponding to each row of splicing nozzles, wherein the closing quantity of the nozzles corresponding to each row of splicing nozzles after adjustment is different from the closing quantity of the nozzles corresponding to the adjacent rows of splicing nozzles.
The step is to adjust according to the number of nozzles to be closed in each row of the spliced nozzles which are initially set, and the closing information of the row of nozzles to be adjusted and adjacent nozzles on two sides of the row of nozzles to be adjusted is considered during adjustment. The adjustment can be sequentially carried out row by row along the moving direction of the spray head during the printing, so that the difference of the closing quantity of the nozzles corresponding to any two adjacent rows of the splicing nozzles after the closing quantity of the nozzles of the last row of the splicing nozzles is adjusted can be ensured.
As shown in fig. 9, in the present embodiment, the step S21: determining the closing quantity of the nozzles corresponding to each row of splicing nozzles according to the printing parameters, the splicing positions and the row of splicing nozzle columns, wherein the method comprises the following steps:

S219; and determining the closing quantity of the nozzles corresponding to each row of splicing nozzles according to the second nozzle row number m, so that the closing quantity of the nozzles corresponding to any adjacent m rows of splicing nozzles is different. The n and m are positive integers.
The step utilizes the second nozzle row number m obtained after adjustment to reset the number of closed nozzles corresponding to each row of spliced nozzles. After resetting, printing can be performed according to the newly set number of closed nozzles, or test printing can be performed according to the newly set number of closed nozzles, and then the number of closed nozzles is continuously adjusted according to the test printing result until the test printing effect meets the requirement, and then formal printing is performed.
As a preferred embodiment m.gtoreq.n, n may take a smaller value and m may take a slightly larger value in this example. The test printing can be started from a smaller nozzle column number, then the value of n is gradually increased according to the printing result until the printing requirement is met, so that the optimal nozzle closing quantity configuration scheme which can meet the printing requirement and simplify the nozzle closing quantity setting can be obtained through continuous test printing. For example, n is set to 2 for a total of 6 columns of spliced nozzles, then test printing is performed, n is modified to 3 if the printing result does not meet the printing requirement, then test printing is performed, n is modified to 4 if the printing result does not meet the printing requirement, and if the printing result meets the requirement, the closing numbers of the nozzles corresponding to any adjacent 4 columns of spliced nozzles can be different.
As shown in fig. 10, in the present embodiment, the printing parameters include the density of nozzles for dot insertion printing along the nozzle row direction, and the S21: determining the closing number of the nozzles corresponding to each row of splicing nozzles according to the printing parameters, the splicing positions and the splicing nozzle columns, wherein the method comprises the following steps:
s210: acquiring the density of nozzles for dot insertion printing along the direction of a nozzle row;
s220: and determining the closing quantity of the nozzles corresponding to each row of splicing nozzles according to the density of the nozzles for inserting point printing along the direction of the nozzle row, the splicing position and the splicing nozzle row.
Although Onepass insertion point printing efficiency is high and printing precision is high, when the number of insertion points is large, the nozzle spray is easier to form a splicing channel. According to the embodiment, the number of the closed nozzles is determined according to the density of the nozzles along the direction of the nozzle row, so that the problem of uneven printing caused by excessive number of the inserted points can be more accurately and effectively solved. For example, the number of nozzle closures may be made proportional to the density of nozzles for dot insertion printing along the nozzle column direction. Or the difference of the closing quantity of the nozzles corresponding to the adjacent two rows of spliced nozzles is in direct proportion to the density of the nozzles for inserting point printing along the direction of the nozzle row. The present embodiment can also set the nozzle-off position according to the density of nozzles for dot insertion printing in the nozzle row direction.
