摘 要：在印刷技術(shù)迅猛發(fā)展和市場競爭日益激烈的今天，CTP技術(shù)是印刷數(shù)字化時代重要的研究與應(yīng)用熱點，也是印刷業(yè)從傳統(tǒng)工作模式轉(zhuǎn)變?yōu)楝F(xiàn)代工作模式的一個重要契機。CTP的種類可以分為多種，且各有優(yōu)缺點，其工藝流程中的關(guān)鍵技術(shù)包括文件輸入處理、頁面拼版、數(shù)碼打樣、色彩管理。本文從CTP制版、印刷和其他方面分析了CTP工藝流程中影響網(wǎng)點復(fù)制的因素，并通過CTP印版成像質(zhì)量控制的實驗，檢測了網(wǎng)點擴大值、實地密度和相對反差值，探討了印版的線性化和印刷網(wǎng)點擴大補償，并提出了制版工藝的優(yōu)化方案。最后總結(jié)了CTP工藝的數(shù)字化、規(guī)范化。

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.
