In the present invention, an ink jet printing apparatus performs ink jet printing using ink jet print heads as shown in fig. 2, each of which is shown in fig. 2(K 0 、C 0 、M 0 、Y 0 And) the nozzle assembly is formed by splicing 3 small rows of nozzles (a, b and c) in a direction perpendicular to the supporting beam 2, and splicing nozzles (overlapped nozzles) exist at the splicing positions of the 3 small rows of nozzles (a, b and c), such as splicing nozzles exist at the splicing positions of the nozzles in the row a and the nozzles in the row b, and splicing nozzles also exist at the splicing positions of the nozzles in the row b and the nozzles in the row c.

specifically, in this embodiment, two adjacent rows of stitching nozzles are located in the same inkjet print head and print the same color ink, and then the number of stitching nozzles and the stitching position can be directly obtained from the inkjet head parameters, for example, the number of stitching nozzles of the row a and the row b in the cyan K inkjet print head in fig. 2 is 3, and the stitching position is the tail end of the row a and the head end of the row b.
In another embodiment, two adjacent columns of stitching nozzles are located in different inkjet print heads and print the same color ink, and then the number of stitching nozzles and the stitching position of the two adjacent columns of stitching nozzles need to be obtained by printing a test chart, such as K in the cyan inkjet print head in fig. 3 0 Row of nozzles and K 1 The number of the splicing nozzles of the row of nozzles is 3, and the splicing position is K 0 End of row of nozzles and K 1 Referring to fig. 7, at the head ends of the rows of nozzles, the number of the splicing nozzles and the splicing position of the two adjacent rows of splicing nozzles in different inkjet print heads are obtained by the following steps:

As shown in fig. 8, which is a test chart formed by printing with the K head that prints black ink in fig. 2, it is apparent from the test chart that the 6 th, 7 th, 8 th, 12 th, 13 th, 14 th line segments are thicker than the other line segments, so that it can be determined that the 6 th, 7 th, 8 th, 12 th, 13 th, 14 th nozzles in the K head are splicing nozzles, the 6 th, 7 th, 8 th line segments are formed by splicing a-column nozzles and b-column nozzles, and the 12 th, 13 th, 14 th line segments are formed by splicing b-column nozzles and c-column nozzles.

the number of the first nozzles is the number of nozzles needing to be closed in the first row of nozzles, and the number of the second nozzles is the number of nozzles needing to be closed in the second row of nozzles.
Specifically, the printing scene is determined according to the printing parameters of the printing, for example, pure color paper or cloth is manufactured by pure color printing, for example, a color image is printed. The method comprises the steps of determining the number of first nozzles needing to be closed in a first row of nozzles in two adjacent rows of spliced nozzles and the number of second nozzles needing to be closed in a second row of nozzles according to a printing scene and the number of spliced nozzles, avoiding splicing channels at spliced positions due to ink discharge of the spliced nozzles, determining the position number of each row of nozzles needing to be closed according to the number of the nozzles needing to be closed in each row of nozzles and the splicing positions, and finally closing the corresponding nozzle according to the position number to enable the corresponding nozzle not to discharge ink in the printing process. Preferably, the number of first nozzles needing to be closed in a first nozzle row of the two adjacent rows of splicing nozzles determined according to the printing parameters and the number of splicing nozzles is X, and the number of second nozzles needing to be closed in a second nozzle row is Y, then X + Y ═ Z, where the number of splicing nozzles is Z, and X, Y, Z are both natural numbers. Furthermore, the first nozzle number X is 0, the second nozzle number Y is Z or the first nozzle number X is Z, the second nozzle number Y is 0 or the first nozzle number X is Z/2, and the second nozzle number Y is Z-X; when the first nozzle number X is Z/2 and the second nozzle number Y is Z-X, the position numbers of the nozzles in the first row that need to be closed and the position numbers of the nozzles in the second row that need to be closed are staggered, specifically, the position numbers of the nozzles in the first row that need to be closed are 1, 3, 5, 7, 9, and the position numbers of the nozzles in the second row that need to be closed are 2, 4, 6, 8, 10.

This facilitates selection and operation.
At this time, if the requirement on the quality of the printed product is high, the number of first nozzles needing to be closed in a first row of nozzles in the two adjacent rows of spliced nozzles is half of the number of spliced nozzles (X ═ Z/2), and the number of second nozzles needing to be closed in a second row of nozzles is half of the number of spliced nozzles (Y ═ Z-X). As shown in fig. 10, in this embodiment, if the number of the nozzles to be spliced is 6, the number of the first nozzles to be closed in the first row of nozzles is 3, the number of the nozzles to be closed in the second row of nozzles is also 3, and the positions of the nozzles to be closed in the two rows of nozzles are staggered, so that the problem that the spliced channel is obvious due to ink discharge from a certain row of continuous nozzles at the spliced position is avoided.
When a color image is printed, if the quality requirement of a printed product is low, the number of first nozzles needing to be closed in a first row of nozzles in two adjacent rows of spliced nozzles is zero, and the number of second nozzles needing to be closed in a second row of nozzles is equal to the number of spliced nozzles;
or alternatively
The number of first nozzles needing to be closed in a first row of nozzles in the two adjacent rows of spliced nozzles is equal to the number of the spliced nozzles, and the number of second nozzles needing to be closed in a second row of nozzles is zero. This avoids the problem of possible blank lines in the staggered nozzle shut-off.
Furthermore, when the requirement on the quality of a color image printing product is high, if all the spliced nozzles for printing a certain color discharge ink, the number of the first nozzles needing to be closed in the first row of nozzles in two adjacent rows of spliced nozzles is half of the number of the spliced nozzles, the number of the second nozzles needing to be closed in the second row of nozzles is half of the number of the spliced nozzles, and the positions of the nozzles closed by the two rows of nozzles are staggered, so that the problem that the spliced channel is obvious due to the fact that ink is discharged from a certain row of continuous nozzles at the spliced position is avoided.
In another modified embodiment, when a color image is printed, the number of first nozzles needing to be closed in a first row of nozzles and the number of second nozzles needing to be closed in a second row of nozzles in the two adjacent rows of spliced nozzles of each color are determined according to the condition of printing the spliced nozzles of each color; when the splicing nozzles of each color correspond to different printing areas, the number of first nozzles needing to be closed in a first row of nozzles in two adjacent rows of splicing nozzles of each color is half of the number of the splicing nozzles, the number of second nozzles needing to be closed in a second row of nozzles is half of the number of the splicing nozzles, and the positions of the nozzles needing to be closed in the two rows of nozzles are staggered; when the concatenation nozzle of every colour corresponds same printing area, then every colour the first nozzle quantity that needs to close in the first row nozzle in the concatenation nozzle of adjacent two is all inequality, can avoid the concatenation lane coincidence of at least two kinds of colours to lead to the concatenation lane to deepen and influence product quality like this. As shown in fig. 11, the nozzles for printing the four inks, cyan (C), magenta (M), yellow (Y), and black (K), are all arranged at the same position, and the number of nozzles for each color is 10, so as to avoid overlapping the lanes L for each color, the nozzles in the row a of the cyan (C) nozzle are closed by 4 nozzles, the nozzles in the row b are closed by 6 nozzles, the nozzles in the row a of the magenta (M) nozzle are closed by 5 nozzles, the nozzles in the row b are closed by 5 nozzles, the nozzles in the row a of the yellow (Y) nozzle are closed by 6 nozzles, the nozzles in the row b are closed by 4 nozzles, the nozzles in the row a of the black (K) nozzle are closed by 3 nozzles, and the nozzles in the row b are closed by 7 nozzles.
