Continuous color chasing method, device and equipment of ink-jet printer, and storage medium

Abstract

The invention discloses a continuous color chasing method, a device and equipment of an ink-jet printer and a storage medium. The method comprises the steps of obtaining initial color values of pixelpoints selected from a to-be-printed image; adjusting the initial color value to obtain a corresponding number of color lump color values; performing printing according to each color block color valueto obtain a plurality of printing color blocks, wherein the plurality of printing color blocks form a color target map; comparing the color target image with a sample image corresponding to the to-be-printed image to obtain a change amplitude value of the initial color value; adjusting a linearization curve of the ink-jet printer according to the change amplitude value to obtain a color chasing curve; and adjusting initial color values of all pixel points in the to-be-printed image according to the color chasing curve. According to the method, only one-time printing adjustment is needed, themethod is simple and rapid, the color chasing curve is obtained on the basis of the multiple pixel points, the color chasing color difference is small, the image restoration effect is good, and the method does not need to depend on skilled color mixing personnel.

Description

technical field [0001] The invention relates to the field of printing, in particular to a continuous color tracking method, device, equipment and storage medium of an inkjet printer. Background technique [0002] In the color management process of color inkjet printers, we can control the output ink volume of each channel of the printer by adjusting the color curve of the printer, thereby controlling the overall printing color effect of the printer. Therefore, controlling the change of the printer's color curve can effectively obtain the printing effect that the user wants, but the purpose of the printer's color curve control is to make the ink volume value input by the printer closer to the actual output ink volume value, thereby ensuring the printing quality. The color is relatively stable. [0003] However, for existing customers who need to print an image with the same color as their sample image or print out a specified color, the customer's requirements cannot be met ...
