摘　　要： 用电子雕刻机在凹版滚筒上雕刻出网穴对角线长度不同的一系列色块,在凹版印刷实验机上用不同粘度的油墨印制实验样张,绘制出印刷特征曲线,从而分析不同粘度的油墨对凹版印刷特性的影响。结果表明:油墨粘度减小导致最小密度值和密度跃升提前,密度饱和段明显,最大密度值减小。 In order to explore the influence of ink viscosity on the printing characteristic of gravure, a series of color batch with different length of ink cell diagonal were engraved on the gravure cylinder by using electronic engraving machine. and the printing samples were made on a gravure press with different viscosity inks and curves of printing characteristic were drawn. The results show that the decrease of ink viscosity have a certain effects on the printing characteristic of gravure such as minimum, maximum and skip of density on presswork.

关 键 词： 凹版印刷 油墨粘度 印刷特征曲线
