激光照排片使用时易产生的弊病及预防措施

Defects Commonly Occurred during Using Phototypesetting Film and their Prevention Measures

激光照排片原来是指用于通过激光进行照相排字的胶片,随着桌面出版系统的推出,现在可以通过计算机直接进行图文处理、拼版、输出激光影像到激光照排片上,制成图文并茂的底片,再把影像晒到PS版上,以获得上机印刷的印版。这项技术系统已在我国印刷行业广泛应用。本文根据多年来对市场技术服务的经验和对市场反映问题的调查研究,将激光照排片在实际应用中易发生的弊病和问题及产生的原因和补救、预防措施进行全面的总结。

Originally, laser phototypesetting film was used solely in laser photo-lettering equipment; following the wide use of computer-based desktop publishing system, now we can combine most preprinting operations through the computer, e.g. original letters and figures processing, make-up etc, and output the image on the phototypesetting film yielding a final negative image which can be printed on a PS plate to make a printing plate for installing on the printing machine. Based on long years＇ technical service and market investigation, this paper presents a comprehensive summary of problems and defects commonly occurred during the use of laser phototypesetting film, their causes and methods of prevention and remedying.
