Problems solved by technology

However, the voltage of the nozzle can only be adjusted within a certain voltage range. If the color difference produced by the nozzle exceeds the range of color difference that can be adjusted by adjusting the voltage, the color difference of the nozzle cannot be adjusted to the normal range.

Abstract

The invention relates to the technical field of inkjet printing, in particular to a color difference processing method, device, inkjet printer and storage medium. The color difference processing method, device, inkjet printer, and storage medium provided by the embodiments of the present invention can determine the abnormal area on the nozzle, and adjust the number of ink droplets ejected by the nozzle holes in the abnormal area within a unit area according to the preset quantity parameters. Quantity, so that the color difference generated when the nozzle prints the target pattern is within the preset allowable range; where, the abnormal area is the distribution area of ​​the nozzle hole that produces the color difference on the nozzle. By adjusting the number of ink droplets ejected per unit area by the nozzle holes in the abnormal area on the nozzle, the color brightness of the nozzle holes in the abnormal area can be printed between the lightness of the lightest and darkest colors that the nozzle can form. Thereby, the calibration range of the chromatic aberration produced by the print head is greatly improved.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a color difference processing method, device, inkjet printer and storage medium. Background technique [0002] Color difference refers to the difference between the color of the pattern on the substrate and the color of the pattern on the original electronic manuscript after a design drawing is printed on the substrate. When the color difference is obvious, it will affect the overall aesthetic feeling of the design and reduce the quality of the product. [0003] The nozzle of the inkjet printer usually includes many densely arranged nozzle holes, and the inkjet printer ejects ink droplets on the printing area on the substrate through the nozzle holes to form a pattern. Due to the fact that the physical processing of the nozzle holes cannot be completely consistent, and the nozzle holes will be worn to varying degrees after a period of use, these will lead to slight diffe...
