摘 要：當(dāng)前的色彩管理技術(shù)主要是基于ICC色彩管理的模式,其工作過程是在對印刷流程中各種環(huán)境與設(shè)備進(jìn)行校準(zhǔn)與規(guī)范化后，記錄它們的色彩特性，生成特性文件（ICC 文件），并通過標(biāo)準(zhǔn)色空間進(jìn)行顏色轉(zhuǎn)換，最終實(shí)現(xiàn)在各種設(shè)備終端再現(xiàn)顏色的一致性。隨著印刷科技的發(fā)展及印刷行業(yè)競爭的日益加劇，印刷企業(yè)的生產(chǎn)方式逐漸從傳統(tǒng)模擬方式走向數(shù)字化、網(wǎng)絡(luò)化與集成化，CTP技術(shù)、數(shù)碼打樣、數(shù)字化工作流程等技術(shù)的應(yīng)用都說明了這一點(diǎn)。本文主要研究數(shù)字化工作流程及輸出設(shè)備的校正和特征化，此外在實(shí)驗(yàn)部分充分了解了數(shù)字化工作流程的工作原理，并通過對印版、印張的網(wǎng)點(diǎn)擴(kuò)大化和印張的色域分析，對采用了色彩管理技術(shù)的CTP和未采用色彩管理技術(shù)的CTF流程的印刷品，進(jìn)行對比，驗(yàn)證了基于CTP流程的印刷色彩管理系統(tǒng)的色彩再現(xiàn)性較好。

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.
