Development Trend of UV Ink

UV ink composition: UV (ultraviolet curing) ink refers to the ink that uses ultraviolet light of different wavelengths and energies to polymerize the monomers in the ink binder into polymers under ultraviolet radiation, so that the ink can be filmed and dried. UV inks also belong to inks. As inks, they must have bright colors (except for special cases), good printability, and appropriate curing and drying rate. At the same time, it has good adhesion, wear resistance, corrosion resistance, weather resistance and other characteristics.

Classification: Classification of printing technology: UV offset printing ink, UV screen printing ink, UV pad printing ink, UV water-based ink-jet ink Application field classification: UV iron printing ink, UV metal ink, UV glass ink, UV plastic ink, UV circuit board ink, UV photosensitive ink Art effect ink: foam oil ink, ice flower ink, hammer print ink, crack ink, crystal ink, varnish The requirements of wrinkle ink and other local gratings on UV varnish. One of the two major new anti-counterfeiting technologies of the new $100 bill is the "3D anti-counterfeiting tape" on the right side of Franklin's head.

With the change of the tilt angle, the pattern of the American Independent Bell and the word "100" in the band will move forward, backward, left and right. Another new anti-counterfeit measure is "the independent clock in the ink bottle", which is located at the lower right of the anti-counterfeit belt on the front of the banknote. There is an independent clock hidden in the copper ink bottle pattern. With the change of the observation angle, the independent clock pattern will change from copper color to green, and will be invisible or visible in the ink bottle accordingly. Composition and classification of water-based UV ink: water-based UV ink is mainly composed of prepolymer (water-based UV curing resin), photoinitiator, pigment, amine, water, cosolvent and other additives.

According to the composition and the dispersion of water in the ink, water-based UV ink is generally divided into the following categories: water-based UV ink emulsified water-based UV ink ionic based self emulsifying water-based UV ink water dispersible resin liquid mixing advantages:

1. Waterborne UV ink can show very fine dots, achieve high-quality printing, and mention high-quality prints

2. Solves the problem that the thickness of UV ink layer is too thick, which affects overprint

3. Ink viscosity and rheology can be controlled with water or thickener

4. The ink has stable performance, which is convenient for practical operation and can obtain stable prints

5. Fast drying speed, which can be stacked and repaired before UV curing, ensuring the smoothness of curing film
