What are the characteristics of Shanrongmo?
Mainly viscosity, adhesiveness, thixotropy and dryness. Characteristics of ink Ink is a kind of slurry viscous substance with certain fluidity. Its viscosity, negative value, thixotropy, fluidity and dryness all determine the performance of ink. Viscosity is a property that prevents the flow of fluid substances, and it is a measure of the ability to hinder the relative motion between fluid molecules, that is, the resistance of fluid flow. The viscosity of ink is related to the transfer of ink in the printing process, the nature and structure of paper, and the viscosity of ink is too large. In the printing process, the transfer of ink is not easy to be uniform, and the paper is napped, which makes the layout flowery and the viscosity too small, and the ink is easy to emulsify and stain, which affects the quality of printing materials. The requirement of ink viscosity in the printing process depends on the printing speed of the printing machine, the degree of paper structure, the change of temperature and humidity in the surrounding environment and other factors.
