摘 要：本文針對目前CTF技術(shù)現(xiàn)狀，優(yōu)化了其工藝過程，以更好地發(fā)揮CTF的作用。分析了影響印刷品質(zhì)量的因素，探討了紙張、橡皮布、油墨等主要問題。在膠印質(zhì)量控制中，利用測控條對PS版的曬版進(jìn)行控制，通過制版工藝的數(shù)據(jù)化與規(guī)范化，達(dá)到完美地再現(xiàn)印品。最后，探討了膠印制版打樣的規(guī)范化。
 菲林的線性化是制版的重點(diǎn)，控制好陽片上網(wǎng)點(diǎn)的變形，對做好出片、制版過程的規(guī)范化和標(biāo)準(zhǔn)化十分重要。PS版曬版時(shí)，需要控制的時(shí)間主要有抽真空時(shí)間、曝光時(shí)間和顯影時(shí)間。曬版時(shí)，這些時(shí)間控制恰當(dāng)，有利于保證曬版的質(zhì)量，并提高曬版的工作效率。在實(shí)際生產(chǎn)中，每次顯影均需要放置測控條，對網(wǎng)點(diǎn)復(fù)制進(jìn)行跟蹤測試，并根據(jù)實(shí)際情況對顯影液進(jìn)行及時(shí)補(bǔ)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.
