Method and system for generating international color consortium profile file

Abstract

The invention provides a method and a system for generating an international color consortium (ICC) Profile file in the color management of printing and digital proofing. The method comprises the following steps of: optimizing a Lab value corresponding to a Neugebauer base color according to the measurement data of a color target diagram and a Neugebauer equation; filtering the measurement data of the color target diagram according to the optimized Lab value corresponding to the Neugebauer base color; and generating the ICC Profile file according to the filtered measurement data. Correspondingly, the invention provides the system for generating the ICC Profile file. The system comprises an optimization unit and a filtering unit. In the method and the system, the Lab value corresponding tothe Neugebauer base color in the color target diagram is optimized by utilizing a Neugebauer equation model, and the measured Lab values of all color blocks are filtered by utilizing the optimized Lab value corresponding to the Neugebauer base color, thereby reducing noise interference in the measurement of the color target diagram and improving the smoothness and accuracy of the measurement dataand the quality of the ICC Profile file.

Description

technical field [0001] The invention relates to the technical field of printing and digital proofing, in particular to a method and a system for generating a color control file in color management, that is, an ICC Profile file. Background technique [0002] Digital proofing is based on the digital publishing and printing system. During the production process of publishing and printing, the graphic information on the page is processed according to the production standards and specifications of publishing and printing, and then the new proofing technology of directly outputting the color sample is used, that is, the digitalized original is used to directly output and print Proofs. It uses a large-format printer to directly output proofing through digital methods to replace the lengthy proofing process of traditional proofing such as film making and printing. Therefore, digital proofing is a key link between prepress and printing in the printing industry, an important means of...

Problems solved by technology

However, when measuring the color blocks in the color target chart, due to the unstable state of the measuring instrument itself, the difference in the use environment, poor paper and ink, etc., the measurement results will deviate from the actual value, and even spike noise will appear, resulting in the inaccuracy of the measurement data. Poor smoothness and accuracy, which affects the final measurement results, resulting in low quality of the generated ICC Profile file
