摘要
通过分析胶印油墨黏度特性以及胶印过程剪切速率状态,并通过实验室测量油墨黏度,获得了油墨由橡皮滚筒向纸张转移过程的黏度。然后配比不同黏度的油墨上机印刷,得到了油墨黏度和印刷品实地密度、网点增大以及色度之间的关系,分析了油墨黏度对印刷质量参数影响的机理,为企业合理使用去黏剂提供依据。
Offset ink viscosity characteristics and the shear rate of printing process were analyzed. The viscosity of ink was measured through experiments and the viscosity of the ink transferred from blanket cylinder to paper was calculated. The same products were printed with different ink viscosities in same condition. The relationships between the ink viscosity and solid density, dot gain and the chrominancc were discussed. The mechanism of the influence of ink viscosity on printing quality parameters was analyzed. The purpose was to provide reference for enterprises to use viscosity reducer reasonably.
