Pigment is a solid component in ink, which is the chromogenic substance of ink, and is generally insoluble in water. The properties of ink color, such as saturation, tinting strength, transparency, etc., are closely related to the properties of pigments.
The adhesive is the liquid component of the ink, and the pigment is the carrier. During the printing process, the binder carries pigment particles, which are transferred from the ink of the press to the substrate through the ink roller and plate, forming an ink film that is fixed, dried, and adhered to the substrate. The gloss, dryness, and mechanical strength of the ink film are related to the performance of the adhesive.
Additives are added to inks to improve the printability of inks, such as viscosity, adhesion, dryness, etc.
