摘　　要：用电子雕刻机在凹版滚筒上雕刻出网穴形状不同的一系列色块,在凹版印刷实验机上印制实验样张,测量出样张各色块的密度值,绘制出印刷特性曲线,从而分析不同网穴形状对凹版印刷特性的影响。结果表明:网穴形状的不同会改变网点密度跃升范围的大小和印品的反差,对凹版图象层次的再现有较大的影响。A series of color batch with different ink cell shapes were engraved on the gravure cylinder by using electronic engraving machine. In order to explore the influence of ink cell shapes on the printing characteristic of gravure, the printing samples were made on a gravure press and curves of printing characteristic were drew. The results showed that ink cell shapes have certain effects on the printing characteristic of gravure such as skip of density and contrast on pressworks.
