不同阶调处的油墨色彩再现性

在IGT AIC2-5印刷适性仪上对4种纸张分别进行油墨色彩再现实验,并进一步测试不同油墨在这4种纸张上的灰度、色强度、色相误差和色效率,对这些油墨色彩再现性指标进行分析。发现在不同的阶调区域,纸张对油墨的色彩再现性存在着较大差异。黄墨在铜版纸上的灰度大于其在胶版纸上的灰度,在胶版纸上的色效率高于其在铜版纸上的色效率,与青墨和品红墨的情况相反。

Analysis of Paper''''s Ink Color Reproduction in Different Printing Tone Areas

Printing ink color reproduction experiments are carried out on four kinds of paper in IGT AIC2-5 tester and the paper's color repro- duction parameters are analyzed,including grayscale,color strength,hue error and color efficiency,which are recommended by GATF.The re- sults indicate that paper's ink color reproduction in different printing tone areas is different.The grayscale of yellow ink on coated paper is greater than on uncoated paper and the colour efficiency of yellow ink on uncoated paper is greater than on coated paper,which is contrary to cyan ink and magenta ink.The results provide reference to establish printing and related standards.
