【摘要】 纸张性能与印品质量密切相关,尤其是纸张光学特性对印刷色彩再现效果有较大的影响。为了分析纸张光学特性对印刷质量的影响,本课题通过喷墨打印实验模拟印刷过程制作了印刷样张,分析了纸张光学特性对印刷色彩再现质量的影响。实验选用了三大类5种不同类型的纸张,测试了每种纸张的表面光学特性,包括白度、色度、不透明度,其后,使用同一喷墨打印机及同种墨水进行了喷墨打印实验,通过色彩管理技术保证输出色彩质量的最优化。通过比较一次色、二次色、三次色和肤色色度再现效果,分析了每种纸张对色彩传递准确性的影响。实验结果表明纸张光学特性对印品呈色效果影响较大。最后,通过理论与实验数据相结合进行分析,研究了印刷纸张光学性能和印品呈色效果之间的关系与影响机理。本研究可以为数字喷墨印刷中合理地选择纸张,提高印刷品质量提供依据,也为后续研究工作提供了基础数据。更多还原

【Abstract】 Paper characteristics are important determinants to print quality,especially the optical characteristics of paper to color reproduction.In order to analyze the correlation between characteristic details and results,a simulation experiment was conducted.Five kinds of paper in three major categories were selected and three major optical characteristics,including whiteness,opacity and chromaticity,were detected.Then a standard digital test format was printed with digital inkjet printer to optimize the output color quality.The tone reproduction and color gamut accuracy were analyzed by comparing the tonal gradation of primary color,secondary color and tertiary color.And the color gamut was created by Verify module in EFI software and was compared by pair-wise comparison analysis.Finally,the primary relationships between paper optical characteristics and tone reproduction were summarized tentatively.The experimental results show that paper whiteness and chromaticity have a significant effect on tone reproduction,yet the effect of opacity is not obvious.This study provides good foundation to further mechanism study in the future work.更多还原
