摘要:信息时代下,计算机技术日益成熟,且广泛运用于印刷业,使得印刷工艺技术渐渐从模拟化转变为数字化,从传统照相制版、电子分色、手工拼版等传统工艺转变为计算机直接制版新工艺技术(CTP)。20世纪初期,德国杜塞尔多夫首次采用了CTP技术,有力地促进了印刷技术的变革,成为了当前印刷行业新趋势。对此,笔者结合日常实际,重点分析了CTP技术在印刷行业中的应用情况。

Abstract: In the information age, computer technology is becoming more and more mature and widely used in the printing industry, which makes the printing process technology gradually change from simulation to digitization, and from traditional processes such as photographic plate making, electronic color separation and manual plate making to new computer direct plate making process technology (CTP). In the early 20th century, Germany Dusseldorf first adopted CTP technology, which effectively promoted the reform of printing technology and became a new trend in the current printing industry. In this regard, combined with daily practice, the author focuses on the application of CTP technology in the printing industry.

纵观传统的凸印(包括柔印)、丝印、凹印和胶印印刷工艺,从制版投入分析,胶印工艺最低。胶印版材不但材料比较轻便、价格低,而且制版操作比较便捷,应用优势及市场潜力较大[1]。尤其是随着CTP技术的日益成熟,其工艺优势渐渐被印刷行业所认可,传统菲林制版已经被淘汰,CTP技术广泛运用于印刷行业,其有力地促进了印刷行业朝着环保、绿色、低碳等方向发展。
1 CTP技术概述
CTP是直接从计算机到制版机制版的一种技术,无需进行胶片制版及拼版生成PS版等工序[2]。CTP制版的主要流程为:以PDF的格式输出数字文件,再把PDF文件导入CTP工作站(直接补漏白、色彩管理、OPI),然后电子拼版,然后再进行数字打样,对蓝纸进行重点查看,一旦发现问题迅速修改,最后把拼好版的文本传输给CTP制版机进行制版,最后上机印刷。这一流程大约花费8~10min。若持续生产,CTP制版机每小时大约会出版二十多张[3]。
不同于传统制版技术,CTP制版技术不但具有时间优势,而且因不再进行菲林、拼版晒版两个环节,制版网点可一次性成像,有效避免了网点丢失、版上脏点等状况。……
