摘　　要：CTcP技术采用普通预涂感光版,在国内印刷市场中的应用正逐渐增加。为了更好地控制网点的复制过程,提高印刷质量,通过实验和对比方法,采用6套不同方案,对测试版进行了输出,探讨了印版网点的复制特性,分析了印版网点的微观结构。结果表明:制版工艺、加网线数、成像分辨率均对网点复制有一定的影响。与传统的CTF工艺相比,CTcP制版工艺的网点复制性能更佳,表现为成像更精确,均匀性更好,阶调复制曲线更平滑,制版过程的可控性更佳。The application of CTcP has been gradually increased in the printing markets because of its compatibility to the traditional Presensitized plate. In order to control the CTcP plate-making process and improve the dot reproduction quality, the dot reproduction characteristics in CTcP and CTF plate-making processes were researched by experimental method, in which a special test form was designed and 6 cases of platemaking experiments were car- ried out. Micro-structures of dots were detail analyzed too. The results showed that the dot reproduction characteristics are influenced by the platemaking process, screen ruling and output resolution. The CTcP process has better performance in dot reproduction with more accuracy, more uniformity, smoother reproduction curve, and better process controllability than CTF process.
