Printing ink is a dispersion of a colored pigment in a liquid, formulated to create an image on a printing substrate. All printing inks consist of four main components: colorants, binders, solvents and additives.
In printing ink production, resins are used for general purposes such as adjusting ink viscosity, ensuring pigment adhesion to surfaces and improving print quality.
Resins used as binders in printing inks contribute to the ink's hardness, gloss, tack and flexibility.
Resins can also be used to give printing inks gloss and opacity. The resin used ensures prints look vivid and attractive.
