Viscosity of Ink
Ink black, ink red, ink blue
Description
The main constituents of ink are pigment, additives and solvent. Small changes in the composition or impure raw materials result in different chemical and physical properties of the ink that might negatively affect the printing process.
Knowing the density and viscosity of ink is of great importance for ink producers because these physical properties provide important information on the quality and utilizability of the raw material and the final product.
