Embodiment Construction

[0019] Please refer to the accompanying drawings for a further description of the present invention.

[0020] like Figure 1b and Figure 2b As shown, the present invention provides a kind of interference inkjet printing method in the variable point printing of inkjet printer, the variable point nozzle of inkjet printer, when printing with uniform dots, add interference spray dots, that is, change the size of the dots at the original average dot distribution position, Make the average total value of the spray points after the change consistent with the average total value before the change point, and keep the color density consistent, that is: the total amount of ink dots in the average distribution per unit area is A=m*m*Dn 2 , where: m is the number of points on a certain side in a unit area; Dn is the size and diameter of a certain n points.

[0021] Taking seven kinds of diameter changes as an example, the total amount of ink dots that interfere with the distribution of ...

Abstract

The invention discloses an interference jet printing method in variable dot printing of an inkjet printer. A variable dot spray nozzle of the inkjet printer provides interference jetting dot during evenly distributing dots for printing, that is, size of the dots at the original evenly distributed dot positions is changed, the average total value of the changed jetting dots is the same as that of the dots before the change so that color depth are identical.

Description

technical field [0001] The invention relates to an inkjet printing method of an inkjet printer, in particular to an interference inkjet method in the variable point printing of the inkjet printer. Background technique [0002] In the variable point printing of the inkjet printer, the size of the spray points can be changed according to the needs. In variable point printing, the commonly used dot distribution method is generally the average dot distribution method, such as Figure 1a , Figure 2a As shown, in order to meet the requirements of different colors, but the positioning requirements are higher. Contents of the invention [0003] The technical problem of the present invention is to provide a method of interfering inkjet printing in variable-point printing of an inkjet printer. [0004] In order to solve the above technical problems, the present invention provides an interference inkjet printing method in the variable point printing of the inkjet printer. The vari...
