油墨叠印的色度评价方法研究

Research of Colorimetric Evaluation Methods for Ink Trapping

从色度角度提出了油墨叠印的三种色度评价方法,通过对这三种色度叠印评价方法的论述和比较分析,认为油墨叠印的密度评价方法存在诸多不足,色度评价方法中的纽纶堡方程预测法对二次色的色度值预测精度不高,而色度叠印和彩度叠印评价方法具有诸多优点,可以用于四色胶印产品的实际检测中。

This paper puts forward three methods for evaluating trapping with colorimetric measurement. After three Colorimetrie evaluation methods for trapping were in detail theoretically and experimentally, discussed, analyzed and compared, the following results were given. First, by the densitometric evaluation methods for trapping there are some shortcomings. Second, the accuracy of eolorimetric values, which are predicted with Neugebauer equations, is not enough. Third, the eolorimetric and chromatic evaluation methods for trapping give lots of advantages and can be used for practical test of printing products.
