Description

UV offset frosted ink

Technical Field

The invention relates to the technical field of new materials, and particularly relates to UV offset frosted ink.

Background

As the printing speed of offset printing machines is getting faster and faster, the demand of printing operators and users of printed matters on the environmental protection performance of products is getting higher and higher, and therefore, the ink production factory is required to improve the quality of offset printing ink without any problem. The ink is required to have good transfer performance, high tinting strength, high drying speed after printing, long on-machine non-skinning time, low heavy metal content in ink products and the like. To meet these requirements, improvements in raw material selection, formulation technology, production process, production environment, etc. must be made, and the production process must be strictly controlled.

UV flexographic inks have a high solids content and a pigment to vehicle ratio prior to curing similar to that of ordinary flexographic inks and were therefore first used in offset printing. The UV offset printing ink has no penetration problem when cured, and can be printed on paper and non-absorbent printing materials. In the prior art, the UV offset printing ink has the problems of poor sand feeling, and non-strong concave-convex feeling, and the reasons are that the raw materials are selected improperly and the formula is set unreasonably. Therefore, the invention aims to develop a brand-new UV offset printing ink formula to better meet the actual requirement.
