摘要
印刷工艺过程中,原件上的连续调画面是通过网点印刷技术转换成印刷制品上的半色调影像的。但是在印刷技术中,制作连续调影像有时也是必要的,譬如制作连续调网目和梯尺等。本文扼要阐述了此制作过程中的一些关键技术问题。
In the printing process, a continuous tone picture image in the original is converted in a half tone image on the printed material by using screen dots printing technique. However, making continuous tone images is also necessary in some special cases, e. g. for making continuous tone screen meshes, step wedges etc.. This paper outlines key technical problems involved in this making process.
