Problems solved by technology

However, even if two scans are printed in one direction, there will still be some errors
[0003] On the other hand, after the printer has been used for a long time, the nozzle may be slightly blocked, or the paper may have a slight error, which will lead to problems such as missing lines. At this time, the printing quality of the overall screen will be greatly reduced. Difficult to be accepted by customers
And if only a small amount of plugging points need to replace the nozzle, the cost is very high for customers

Abstract

The invention relates to a printing uniformity correction method, comprising: receiving and confirming printing parameters; generating a printing template for processing each nozzle data of the printer according to the printing parameters, and the printing template splits the printing data points into N parts, wherein N is an integer and N≥2; and the print data points split into N parts are divided into N times for printing. Compared with the prior art, the present invention can effectively disperse errors and improve printing effect. In addition, the present invention also relates to a printing uniformity correction device, medium, equipment, system and printer.

Description

technical field [0001] The invention relates to a printing uniformity correction method, device, medium, equipment, system and printer. Background technique [0002] In inkjet printing, due to factors such as color coverage sequence and ink characteristics, it is difficult to ensure that there will be no color difference. Especially in bi-directional printing, due to factors such as the color sequence of the nozzles, the speed of movement, and the ink itself, it is easy to produce color differences in the printed screen when moving to the left and right, thus affecting the overall printing quality. Take the commonly used YMCK mode as an example. In terms of the superimposition order of colors, if the colors are arranged as YMCK, then the last covered color is K color when moving to the left, and the last covered color is Y color when moving to the right. This results in a darker color when going to the left, and a lighter color when going to the right. In addition, when th...
