摘　　要：借助网点形状函数并利用PostScript语言编程,实现了若干种形状随阶调值变化的网点的制作,实验检测比较表明,其中变椭圆形网点的阶调传递特性相对较好。Some types of shape dots which change with tone value are implemented by mease of dot shape function and Postscript language,comparasion of the experiment resule shows that tone value transmission characteristic of elliptical dot is better.

关 键 词：网点形状 POSTSCRIPT语言 网点函数
