Viscosity: is disrupting the flow of a fluid in nature, is a fluid interaction between molecules and prevent measure of relative motion between the molecules, namely resistance to fluid flow. The viscosity of ink in printing ink transfer, the nature and structure of the paper there are important relationships, viscosity of the ink, printing ink transfer not in uniform, and picking the phenomenon of paper, making flooding and layout; small viscosity, ink easily emulsify, dirty, affect the print quality. Size on the viscosity of ink during the printing process requirements, depending on the printing speed of the printing press, paper structure on the software level, changes in ambient temperature and humidity, and other factors.
