Viscosity is also known as viscosity (hysteresis) or internal friction. A property of a fluid (including liquid and gas) that hinders its relative flow. When a liquid is agitated, its flow velocity is proportional to the one used, Ma, the force used (shear stress) = constant x shear rate.
The viscosity is mainly determined by the composition of the ink. For example, if the viscosity of the binder in the ink is high, the viscosity of the ink is also large; in addition, the solvent content is more, the viscosity is small; the pigment content is large, the viscosity is also large; the higher the workshop temperature, the lower the meal degree, etc.
Ink viscosity is also known as adhesiveness. It refers to the ink in the printing process, between the ink set and the ink roller, between the ink roller and the plate, between the printing plate and the object to be printed. At the moment of the separation of the ink film, the ink molecules produce a force to resist the separation of the ink layer, which is called the adhesion of the ink.
