Inkjet printer color tracking method, system, storage medium and color tracking device

Abstract

The invention relates to an inkjet printer color tracking method, system, storage medium and color tracking device. The method includes acquiring the original spectral data printed by the target printer and the color tracking printer respectively, and preprocessing the spectral data; according to the preprocessing Generate the color-chasing lookup table of the color-chasing printer from the final spectral data; control the color-chasing printer to print the target image according to the color-chasing lookup table. The inkjet printer color tracking method of the present invention obtains and preprocesses the spectral data of the target printer and the original state of the color tracking printer, and then establishes a color tracking lookup table of the color tracking printer according to the preprocessed original state spectral data, and According to the color tracking lookup table of the color tracking printer, the target picture is printed, which realizes the automatic and efficient color tracking of the inkjet printer, without relying on senior color correction personnel, simple operation, cost saving, and small color difference in color tracking, and the restoration effect of the grayscale image it is good.

Description

technical field [0001] The invention relates to the field of printing technology, in particular to an inkjet printer color tracking method, system, storage medium and color tracking device. Background technique [0002] Inkjet printers are widely used in outdoor advertising, label printing, textile printing, ceramic printing, printed electronics, home decoration and other fields. When mass production is carried out in industry, it is usually required that multiple printers can print out samples with consistent colors, and it is required that the printed color after a period of use is consistent with the color of the previously determined print sample. Generally, the state of the printer is not stable, and it is usually affected by factors such as ambient temperature, humidity, nozzle aging, etc., and changing the ink and paper will also change the color of the printed sample to varying degrees. How to ensure that multiple printers can print consistent colors in different ti...

AI Technical Summary

Problems solved by technology

[0003] (1) Color correction personnel repeatedly try different ink volume ratios according to the printing results, and experienced color inspectors need to spend a lot of time and energy to adjust the ink volume curve of the printer;

[0004] (2) Adjust the pixel value in the picture according to the actual printing results. This method is only suitable for small production volumes. If a large number of pictures need to be printed, the staff needs to process each picture for each printer, and the workload is huge;

[0005] (3) The characteristic file of the printer is used to generate the link characteristic file. Although the operation method is simple, there is a certain degree of color cast problem, and the restoration effect of the gray scale is not ideal. It is difficult to popularize and apply in actual production.
