CTF制版工艺的数字化与标准化探讨

文档编号:YS032  文档字数:12933.页数:28

摘 要：本文针对目前CTF技术现状，优化了其工艺过程，以更好地发挥CTF的作用。分析了影响印刷品质量的因素，探讨了纸张、橡皮布、油墨等主要问题。在胶印质量控制中，利用测控条对PS版的晒版进行控制，通过制版工艺的数据化与规范化，达到完美地再现印品。最后，探讨了胶印制版打样的规范化。
 菲林的线性化是制版的重点，控制好阳片上网点的变形，对做好出片、制版过程的规范化和标准化十分重要。PS版晒版时，需要控制的时间主要有抽真空时间、曝光时间和显影时间。晒版时，这些时间控制恰当，有利于保证晒版的质量，并提高晒版的工作效率。在实际生产中，每次显影均需要放置测控条，对网点复制进行跟踪测试，并根据实际情况对显影液进行及时补充。

Abstract：In this paper, according to the technical status of current CTF, optimize its processes to bring CTF into play. Analysis the factors of what affect print quality, probe the paper, blanket, ink and other major issues. Within the offset printing quality, take advantage of control strip on the PS version, by the way of plate-making process and standardization of data， then achieve a perfect reproduction of printed materials. Finally, discussing the standardization of offset plate proofing.
 The linear film is the key to make plate, subject the network deformation of positive film, is meaningful to do the normalization and standardization of making film or plates well. When proofing plates, is need to control the vacuum time, exposure time and developing time of PS version. Appropriate time control is good for ensuring the quality of printing down and increase the efficiency. In the actual production, each imaging are required to place control strip, copy of the network to track test and in line with actual situation, timely complement to the developer solution.
