Embodiment Construction

[0047]The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Apparently, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0048] In order to improve the consistency between the proofing color and the printing color, the present invention proposes a color correction method for digital proofing equipment, which is applied to the pre-press processing flow. Specifically, the color correction is divided into two stages. The first stage performs color correction once, and the second stage The secondary color correction is carried out in the first stage, and the primary color correction stage includes multiple steps. ...

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. [0003] Different colo...
