Prepress production has been mostly digitalized because of the invention and developing of typesetter technology, computer to plate technic has digitalized platemaking process too, the appearance of digital press makes digitalization possible in printing process. For their characteristics, the traditional control strip can't be used in digital platemaking and printing, therefore, we should design PostScript printing control strip as a way to control quality during production.
激光照排技术的发明和发展使印前工艺过程已经基本实现了数字化,CTP技术又将制版工艺带入数字时代,数字印刷机的出现为印刷工艺进入数字化提供了可能,由于它们的作业特点,用于传统印刷的控制条无法作为其制版、印刷质量检验与控制的手段,这就需要我们设计出既能控制印刷过程又能控制制版质量的PostScript印刷控制条。
