What are the main ingredients of ink?
In the process of printing, binders carrying pigment particles from the printing machine roller, ink half the plate, was removed to the substrate to form ink film, fixing, drying and adhesion to the substrate. The gloss, dryness, mechanical strength and other properties of the ink film are related to the properties of the binder. The additives added in ink are to improve the printability of ink, such as viscosity, adhesiveness and dryness. The configuration of ink technology is more complex, is generally pigments, binders and additives, according to a certain proportion, first in the inking machine oil mixed into a paste, then the roller type grinding machine or repeatedly grinding, the fine particles of pigment, uniformly dispersed in the binders made.
The additives added in ink are to improve the printability of ink, such as viscosity, adhesiveness and dryness. With the development of printing technology, the varieties of ink are increasing, and the classification methods are also many. If the printing types has the following five types: letterpress printing ink and black ink, rotary black ink, color printing ink; offset printing ink: offset light resin ink, offset printing ink; gravure printing ink: rotogravure printing ink, intaglio ink; printing ink: ink stencil hole. Print ink; special printing ink: foaming ink, magnetic ink, fluorescent ink, conductive ink etc.. Pigment is a solid component in printing ink, which is a pigment that is not allowed to be used in water. Ink saturation, tinting strength, transparency and other properties are closely related to the properties of pigments. The binder is the liquid component of the ink and the pigment is the carrier.
