CTP制版工艺的数字化与标准化探讨

摘 要：在印刷技术迅猛发展和市场竞争日益激烈的今天，CTP技术是印刷数字化时代重要的研究与应用热点，也是印刷业从传统工作模式转变为现代工作模式的一个重要契机。CTP的种类可以分为多种，且各有优缺点，其工艺流程中的关键技术包括文件输入处理、页面拼版、数码打样、色彩管理。本文从CTP制版、印刷和其他方面分析了CTP工艺流程中影响网点复制的因素，并通过CTP印版成像质量控制的实验，检测了网点扩大值、实地密度和相对反差值，探讨了印版的线性化和印刷网点扩大补偿，并提出了制版工艺的优化方案。最后总结了CTP工艺的数字化、规范化。

Discussion on CTP digitalization and standardization

Abstract: Nowadays, with the rapid development of printing technology and drastic business competition, the CTP technology has become an important topic of research and application in the era of digital printing. It's also a good chance for graphic art to change from the traditional mode to a modern one. CTP can be divided into many types, and each CTP technology had its own advantages and markets. The key technologies of CTP process include files imputing and processing, pages make-up, digital proofing, and color management. Form the angles of plate-making, printing and digital image presetting, the factors which impact dot reproduction results in CTP process were analyzed in this article. The experiment of imaging quality control by CTP process was carried out, and dot gain, solid ink density and relative contrast value were tested, the linear of plate and dot gain compensation were discussed, the optimum proposal of plate –making process was proposed. In the end, the CTP digitalization and standardization were summarized.
