How is uv ink made?For uv ink, color, bone and drying is the three most important properties

of ink, but also the development of ink formula and process and production ink should pay attention to.

Resin: connecting material is a kind of colloidal fluid, its role is first as a pigment carrier,

the pigment powder and other solid particles mixed together; Secondly, as an adhesive,

the pigment can finally be fixed on the surface of the substrate, so as to achieve the purpose

of displaying text, images, decoration, etc. The resin in the connecting material can form a

thin transparent film layer, which is also the reason why the ink can be printed on the film.

Therefore, the choice of resin solution will affect the final performance of the ink, such as

drying speed, stability, gloss, etc.

How is uv ink made?，In ink, solvent is used to dissolve resin film forming material and

make solvent - based bonding material. In plastic gravure ink, solvent can not only dissolve

a variety of film forming polymer, adjust the viscosity and fluidity, but also has an important

impact on the film quality, but also plays a decisive role in the drying speed of ink. In plastic

gravure ink formula, one of the key technologies is to choose the right solvent.

The colored materials used in printing ink are pigments, which are divided into inorganic

pigments and organic pigments. At present, the pigments used in printing ink are mostly

organic pigments. In the production of printing ink, the pigment is dispersed in the connecting

material, and then printed on the surface of the substrate, so that the printing product presents

a colorful image. Many properties of ink are related to pigments, such as the relative density

of ink, transparency, light resistance, heat resistance and resistance to chemicals. In a sense,

the pigment determines whether the produced ink is suitable for a printing process or to meet

the end use of the printed product.

Additives are the auxiliary components of ink, adding additives to the main purpose is to

improve the stability of ink, printing performance, imprinting surface performance and so on.

There are many kinds of additives, mainly plasticizer, desiccant, surfactant, dispersant and so on.
