摘要
印刷行业对于印刷品加网线数和加网角度的识别目前还主要依靠经验。利用莫尔条纹原理,通过设置合理的印刷加网线数、加网角度、激光照排机输出点数,设计了评价图像质量的印刷网线尺,对印刷品加网线数和加网角度可以量化测试,对于生产实践具有很好的指导作用。
At present, identification of screen line and angle for the print products is mainly depended on experience in printing industry. Screen line ruler for image quality evaluation was designed using Moire fringe principle and through setting suitable screen line number, screen angle, and output line number laser typesetter. The ruler can be used to measure screen line number and screen angle quantitively, which has an important guiding significance for printing practice.
