Abstract: The current color management technology is based on the model of ICC color management, the course of their work is in the process of printing a variety of environmental and equipment calibration and standardization, the record of their color characteristics, to generate properties files (ICC files), and through standard color space for color conversions, and ultimately end in a variety of equipment, the consistency of color reproduction. With the development of printing technology and printing industry increased competition, the production of printing enterprises from traditional analog to digital, networked and integrated, CTP technology, digital proofing, digital workflow applications and other technology described in this point. This paper studies the digital workflow and output device calibration and characterization, in addition to fully understand the experimental part of the digital workflow of the working principle, and through the plate, sheet and sheet of the network expansion of the color-domain analysis of the use of the CTP technology, color management and color management techniques did not use the CTF of print process, compared to verify the process based on the CTP printing color management system and better color reproduction.
