摘要: 油墨的印刷适性与其流变学特性密切相关。利用流变学实验手段研究胶印红墨的粘度、触变性、粘弹性对油墨墨性的影响,从而得出了好油墨的共性指标。Abstract: The printing properties of inks are closely associated with its rheological behavior.The effects of viscosity,thixotropy and viscoelastisity on the offset inks were studied.The experimental results showed that the advanced offset inks should have the properties of higher shear viscosity with lower temperature coefficient,appropriate yield stress,thixotropy,and small sensitivity of shear loss modulus to frequencies.
