Ink jet printer color tracing method and system, storage medium and color tracing device

Abstract

The invention relates to an ink jet printer color tracing method and system, a storage medium and a color tracing device. The method comprises the following steps: acquiring spectral data of an original state printed by a target printer and a color tracing printer, respectively, and preprocessing the spectral data; generating a color tracking look-up table of the color tracking printer according to the pre-processed spectral data; controlling the color tracking printer to print the target picture according to the color tracking look-up table. According to the ink jet printer color tracking method, the spectral data of the original states of the target printer and the color tracking printer is acquired and is preprocessed , then according to the spectrum data of the original state after thepretreatment, the color tracking look-up table of the color tracking printer is established, according to the color tracking table of the color tracking printer, the automatic and efficient color tracking of the ink jet printer is realized, and the operation is simple, the cost is saved, the color difference of the color tracking is small, and the restoration effect of the gray-scale image is good without relying on the senior toner.

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.
