Improved color management method for digital proofing

Abstract

The invention discloses an improved color management method for digital proofing. The method comprises the following steps: printing an IT8 color test table by means of printing equipment, adopting digital output equipment to print an IT8 color test table in a condition without color management, utilizing a color test spectroscope to test the two IT8 color test tables and then obtaining an ICCProfile of the printing equipment and ICCProfile of the digital output equipment, performing color adjusting on a color management platform, obtaining a corrected ICCProfile of the current printing equipment in a current state, and printing a digital proofing draft by means of the digital output equipment in a condition of the finally determined ICCProfile. The improved color management method effectively overcomes the disadvantage that the deviation between data reading and analysis errors and IT8 color test table printing by printing equipment causes an ideal result of a digital proofing draft. Moreover, the method is applied to color management for advertisement painting, artwork simulation or the like.

Description

technical field [0001] The invention relates to an improved color management method in digital proofing. Background technique [0002] In the printing industry, prepress proofs (final contract proofs) have two main functions: to allow users to see the printing effect of the final printed matter in advance, and to confirm the design; Reference object, and use it as the test standard for the final printing effect. [0003] The production process of traditional pre-press proofs is similar to real printing, and it also needs to be separated and produced, which mainly depends on the feeling, experience and skills of the proofing operator. Not only the cost is high, but also the cycle is long and the efficiency is low. Digital proofing is an efficient and high-quality advanced working method for making pre-press proofs, and has become the main way of making pre-press proofs in the printing industry. [0004] Digital proofing is a technology that directly outputs proofs on the p...

Problems solved by technology

[0010] In order to solve the above-mentioned existing shortcomings, the main purpose of the present invention is to provide a practical and improved color management method in digital proofing, which can effectively overcome the errors in data reading and analysis caused by color measurement and spectroscopic instrument measurement and printing equipment printing IT8. There are also deviations in the color test table, resulting in the unsatisfactory defect of the result of the digital proofing draft. At the same time, the present invention can also be applied to the color management of advertising printing, artwork simulation, etc.
