Color correction method for digital sample printing equipment

Abstract

The invention provides a color correction method for digital sample printing equipment. The method comprises the following steps: generating and configuring a linear curve, total ink and a grey balance calibration file of the digital sample printing equipment in sequence; generating an equipment connection ICC profile according to a generated ICC profile of the digital sample printing equipment and a generated ICC color profile of printing equipment in order to finish primary color correction; and when a trigger condition is satisfied, regenerating a linear curve and a grey balance calibration file in a current sample printing environment by using relevant parameters recorded during primary color correction, and configuring the regenerated linear curve and grey balance calibration file on the sample printing equipment. During secondary color correction of the sample printing equipment, a total ink value and a color separation file do not need to be reconfigured, and color matching between the digital sample printing equipment and the printing equipment does not need to be performed once again, so that color correction flow is simplified, and the color correction time is saved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a color correction method for digital proofing equipment. Background technique [0002] Digital proofing refers to a new type of proofing technology that is based on the digital publishing and printing system. During the publishing and printing production process, the graphic information on the page is processed according to the publishing and printing production standards and specifications, and the color proof is directly output. It uses a large-format printer to directly output proofs through digital methods to replace the traditional lengthy proofing processes such as film making and printing. The digital proofing system is generally composed of a color inkjet printer or a color laser printer, and through color printing and simulating the color of the printing proof, the digitalized original (electronic file) is used to obtain the verification proof.
