铜版纸性能参数与静电照相数码印刷色彩再现的实验研究

Experimental Study on the Influence of Coated Paper Performance Parameter to Color Rendering of Electrophotographic Digital Printing

以白度和不透明度基本相同的高光铜版纸和亚光铜版纸作为研究对象,通过实验和趋势对比法,研究铜版纸的性能对静电照相数码印刷机色彩再现的影响。结果表明:在纸张白度和不透明度基本相同的情况下,其原色墨的色强度、色效率、色纯度、灰度和色相差基本保持稳定;黄墨的色强度、灰度和色相差最小,色效率和色纯度最高,而品红墨的色强度、灰度和色相差最大,但色效率和色纯度最低。

By means of experiment and method of tendency contrast,taking high gloss and semi-gloss coated paper with basically identical whiteness and opacity as the research objective,the authors studied the influence of performance of coated paper on the color rendering of electrophotographic digital printer.The result shows that the color strength,color efficiency and color purity as well as grayscale and hue difference of ink with primary color are basically kept stable under the circumstance of identical whiteness and opacity of coated paper.Meanwhile,color strength,grayscale and the hue difference of yellow ink are the smallest,and the color efficiency and color purity of yellow ink are the highest.The color strength,grayscale and hue difference of magenta ink is the greatest,and the color efficienc and color purity of magenta ink are the lowest.
