Ink components are as follows:

Pigment is the solid component of ink, ink color material, is generally insoluble in water pigment. Ink color saturation, tinting force, transparency and other properties and pigment performance has a close relationship.

Binders are the liquid components of ink, pigment is the carrier. In the printing process, the binders carry pigment particles from the ink of the printing press through the ink roller, the plate, and onto the substrate to form an ink film, which sticks, dries, and adheres to the substrate. The gloss, dryness, mechanical strength and other properties of the ink film are related to the properties of the binder.

Ink additives are added to improve the printing suitability of ink, such as viscosity, adhesion, dryness, etc.

With the development of printing technology, the variety of ink is increasing, classification methods are also many. If according to the way of printing, there are five kinds of classification:

Relief printing ink: book black ink, rotary black ink, color relief ink, etc.

Lithographic printing ink: offsctdruckereien resin ink, offsctdruckereien rotary ink, etc.

Gravure printing ink: photogravure ink, engraving gravure ink, etc.

Hole printing ink: stencil ink, screen printing ink, etc.

Special printing ink: foaming ink, magnetic ink, fluorescent ink, conductive ink, etc.

Ink configuration process is more complex, generally the pigment, binders and various additives, in accordance with a certain proportion, first mixed in the ink mixing machine into oily paste, and then repeatedly rolled in the roller grinder or grinding, so that the pigment to fine particles, evenly dispersed in the binders and made.
