摘要
测试了70 g/m2胶版纸和157 g/m2铜版纸的平滑度、光泽度和油墨吸收性等参数及其打印纸样不同区域的网点百分比和各实地色块的三刺激值,通过计算它们的网点增大值和x、y色度坐标,绘制了不同印样的网点扩大曲线和色域图。研究结果表明,当印刷条件相同时,由于157 g/m2铜版纸具有较高的平滑度、光泽度和较小的油墨吸收性,其网点扩大值较小,色域范围较大,故印刷网点复制效果较好;而70 g/m2胶版纸的平滑度、光泽度等指标均低于铜版纸,油墨吸收性较大,因此其网点扩大值较大,色域范围较小。
The properties of art paper and offset paper including brightness, smoothness, gloss and absorbability, dot percentage and the tristimulus values of every dot areas and solid areas of the printed paper samples were measured. Dot gain curve and chromatic diagram were drawn after dot gain values and chromatic coordinates （x, y） were calculated. The results showed that smaller dot gain value and greater gamut of color occur on the art paper due to its higher smoothness, gloss, brightness and lower absorbability when the printing conditions are the same, so the printing dot reproduction quality on the surface of art paper is better. However because offset paper has lower smoothness, brightness and gloss, higher absorbability compared with art paper, therefore dot reproduction quality on offset paper is not as good as art paper.
