铜版纸与哑粉纸印刷复制特性研究

Study on Printing Properties of Coated Art Paper and Matt Art Paper

采用实验方法,对铜版纸和哑粉纸的印刷复制特性进行了测试和比较。结果显示,2种纸张的最佳印刷反差和实地密度略有差异;在相同的印刷条件下,与铜版纸相比,哑粉纸印刷品相对反差大,网点扩大小,叠印率、颜色亮度、总油墨覆盖率高,色差小,但颜色饱和度低,局部范围色域较小。为了获得最佳的印刷效果,应该采用不同的印刷参数,适当增加哑粉纸的用墨量。

Printing characteristics of coated art paper and Matt art paper were tested and compared. The resuhs showed that the optimum relative contrasts and solid densities of these two kinds of paper is slightly different ; the prints on Matt art paper have relatively higher relative contrast, smaller dot gains, higher ink trappings, higher brightness and larger total dot area coverage, smaller color difference, lower color saturation, and smaller color gamut at local scope than those on coated art paper under the same printing conditions. Different parameters should be taken to achieve best printing results, and thicker ink film should he applied for matt art paper than coated art paper.
