What is UV offset ink and how does it work?

Sep 05, 2025

UV-LED eco-friendly ink is an environmentally friendly ink that cures in an extremely short time using ultraviolet light (UV-LED light source). It is primarily composed of a photocurable resin, reactive diluent, photoinitiator, colorant, and additives. It offers energy-saving, solvent-free, and environmentally friendly features. The curing process of UV-LED eco-friendly ink eliminates the need for traditional drying equipment. Instead, it achieves a rapid transition from liquid to solid through a photoinduced cross-linking reaction, typically in under one second.

A leader in this field, Daihei ink delivers premium UV ink solutions tailored for diverse industries. Its UV inks excel in packaging (flexible films, cartons), commercial printing (posters, brochures), and industrial applications (electronics, automotive parts). For example, Daihei’s UV curable inks are ideal for food packaging, meeting strict safety standards while maintaining vivid graphics. They also perform exceptionally well on non-porous materials like plastic and metal, a key advantage for product labeling.

Using UV ink effectively requires matching the ink type to the substrate—Daihei offers specialized formulas for different surfaces. Ensure proper UV lamp intensity (300-400nm wavelength) and adjust printing speed for full curing. Regular maintenance of printheads and UV systems preserves ink flow and curing efficiency. With Daihei ink’s reliability and UV technology’s benefits, businesses achieve high-quality, sustainable printing results.
