Printing Ink is a complex mixture of ingredients (Pigments, Resins, Additives & Solvents) that are combined in a specific formulation to meet desired characteristics of the printing application of the ink. The function of the pigment is to provide the coloristic properties of the ink. The resin is added as a dispersion aid and also as a binder to affix the pigment to the substrates. The solvents are transferring the pigment and resin through the press to the substrates also control viscosity and flow of ink. Additives are used for some special characteristics according to application of ink.
