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。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 output should accord to the input, the output, the printability, and the optical resolution＇s factor. Thus, this article could offer some scientific and reliable suggestion for the pre-pressed system＇s scanning resolution setting.
