Kinds of Ink by Printing Methods

Offset Printing Ink

Offset printing  ink is a viscous and viscous ink, mostly oxidation junction film drying ink, which has good resistance to water. It can be divided into sheet-printing ink and roll-printing ink, the former is mostly fast-drying oxidation conjunctive film ink, the latter is mainly based on permeation drying. It can also be divided into offset glossy resin ink, offset rotary ink, etc.

Relief Printing Ink

Relief printing ink is a viscous ink that has a wide range of viscosity variation, which is related to the printing speed of the press. It dries in several ways, including osmotic drying, oxidation conjunctive drying, volatile drying, or a combination of several ways. Letterpress inks include rotary black ink, booklet black ink, color letterpress ink, etc.

Gravure Ink

Gravure ink It can be divided into two major categories, one is gravure ink, the other is engraved gravure ink. The former is a very thin fluid, viscosity is very low, completely rely on solvent volatilization drying, is a volatile drying ink, can be printed on non-absorbent substrates; the latter higher viscosity, yield value is relatively large, without greasiness, basically rely on oxidation conjunctive drying.

Special Printing Ink

Many special inks need thicker inks to perform well, and can be divided into foaming inks, magnetic inks, fluorescent inks, conductive inks, etc. It needs to have no volatile solvents, no odor, no blocking, fast curing speed, strong water resistance, brilliant colors, etc.
