中文摘要:
      在凹版印刷中,图像层次的变化,取决于墨层厚度的变化,而墨量不象其它印刷方式一样可以在印刷过程中调节,而是取决于网穴的体积和油墨的转移率。针对凹版印刷过程中影响油墨转移的主要因素,用凹版印刷适性仪进行了打样,测量了样张的墨层厚度,计算了油墨转移率,用油墨转移率定量分析了承印物的性质、油墨粘度、印刷压力、印刷速度对凹版印刷油墨转移的影响,从而探讨了凹版印刷油墨转移的规律和特性。
英文摘要:
      In gravure printing, the image-level changes are determined by changes in ink film thickness. Unlike other printing modes, ink quantity of gravure printing can not be adjusted in printing process, which is determined by the volume of cell and ink transfer rate. Gravure printing test equipment was applied to make sample sheets. The ink film thickness of the sample sheets was measured and ink transfer rate was calculated. The influences of the nature of substrate, ink viscosity, printing pressure, and speed of gravure printing on ink transfer were analyzed quantitatively with ink transfer rate. The transfer of rules and characteristics of gravure printing ink were discussed.
