【摘要】 扫描分辨率是衡量图像细节表现力的重要技术参数。在彩色桌面印前系统中,图像扫描输入、加网线数、灰度等级和照排机输出都与扫描分辨率有关。指出设置用于印刷输出的扫描分辨率要遵循"输入决定分辨率"、"设备决定分辨率"、"印刷适性决定分辨率"、"用整除光学分辨率扫描"等原则,为印前技术人员高质量地进行扫描提供科学依据和理论指导,对生产实际操作具有指导意义。更多还原

【Abstract】 The scanning resolution is the key technical parameter in determining the detailed quality of pictures.In the pre-pressed DTP system,image-input,line-screen level,gray level and image-output are all concerned with the scanning resolution.This paper indicates that the setting of the scanning resolution for out- put should accord to the input,the output,the printability,and the optical resolutions factor.Thus,this arti- cle could offer some scientific and reliable suggestion for the pre-pressed system’s scanning resolution setting.更多还原
