摘　　要：通过设定相同的印刷条件和印刷过程,控制同种纸张上ABC 3种不同油墨的网点扩大参数,测量了样张上的色块和梯尺,得到了不同油墨的相对反差值与网点扩大曲线图,并比较了3种油墨的色域图。结果表明:A墨黑色网点扩大最严重,C墨黄色网点扩大最严重,B墨四色网点扩大最为均匀和平滑;B色油墨除了黄色反差较小外,其余三色相对反差最大;整个图像阶调范围内A油墨的色域图最小,B油墨的色域图最大且最平滑,因此B油墨的印刷性能最佳。Dot gain parameters of three different kinds of ink on the same paper were controlled by setting the same printing conditions and controlling process. Different ink contrast and dot gain curves were obtained by measuring color patch and color ladder＇s dot area rate On the test form. The results showed that the black dot gain rate of ink A is the most seriously; the yellow dot gain rate of ink C is the most seriously dot gain rates of ink B are the most smoothly and regularly except the yellow relative contrast, other three relative contrast of ink B is biggest ink A has the minimum color gamut on the whole image tone range, while ink B has the maximum and the smooth color gamut. So ink B has the best printing performance.
