Where are The Application Areas of UV Offset Printing Inks?
The use of UV offset printing ink:
UV offset printing ink refers to the ink that is instantly cured by UV light irradiation. The main components of UV offset printing ink include pigments, oligomers, monomers (reactive diluents), photoinitiators and various auxiliaries. Among them, resins and reactive diluents play the role of fixing pigments and providing film-forming properties; pigments give ink moderate color and covering power to the substrate; photoinitiators are required to absorb photons to initiate polymerization under the interference of pigments.
From the perspective of printing process, UV offset printing ink has fast fixing speed, good conjunctival performance, good adhesion to various printing materials, and has better scratch resistance, abrasion resistance, acid and alkali resistance than ordinary inks. Therefore, , although its price is much more expensive than ordinary ink, it is still widely used.
At present, the fields of UV ink printing are as follows:
1. Non-absorbent material printing
Such as polyethylene (PE) film, polyvinyl chloride (PVC) film, polypropylene (PP) film, metal foil and non-absorbent special materials. If these printing materials are printed with ordinary solvent-based inks, they need a certain drying time, and usually need to use powder spraying, drying racks, or add other additives to the ink, but UV inks have no such troubles at all.
2. Commercial paper printing
The printing materials and inks used in commercial paper printing are relatively special, such as carbonless copy paper, thermal paper, magnetic ink, anti-counterfeiting ink, etc., and the ink is required to have certain discoloration resistance, heat resistance and stability, so it is better to use UV offset printing ink or UV varnish. At the same time, due to the high speed of the ticket printing equipment and the small amount of ink, it also has the favorable conditions for printing with UV ink.
3. Metal material printing
When the surface of metal material is printed with UV special ink, the curing process can be shortened and the original curing device can be simplified. At the same time, the good curing and conjunctival properties of the UV ink surface layer can not only improve the post-press processing characteristics, but also improve the appearance quality of the product.
