| 中文摘要: |
| 印刷行业目前还主要依靠经验进行印刷品加网线数和加网角度的识别。 根据莫尔条纹原理,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。 主要对前期设计的网线尺进行数学公式的推导,对印刷品加网线数和加网角度测试提供充分理论依据。 |
| 英文摘要: |
| At present, identification of screen line and angle is mainly depended on experience in printing industry. Screen scale for evaluation of print quality was designed through setting of suitable screen number, screen angle and output points of laser phototypesetter according to Moire fringe principle in earlier study. Mathematical formula for the screen scale was deduced. The purpose was to provide theoretical foundation for testing of screen number and screen angle of printing material. |
