Application & Solutions

UV printing is a printing technology that uses ultraviolet (UV) light to achieve instant curing and drying of ink. The following is a related introduction:

• The ink used in UV printing contains ingredients such as photoinitiators, prepolymers, and diluents. During the printing process, after the ink is transferred to the surface of the substrate, it is irradiated by ultraviolet light emitted by the UV light source. The photoinitiator absorbs ultraviolet energy to produce active free radicals or ions, which trigger polymerization reactions between the prepolymer and the diluent, and the ink is instantly cured into a solid state, thus completing the printing process.

Features

• Fast drying speed: The ink can be cured in a very short time, which can achieve high-speed printing and improve production efficiency.

• Good environmental performance: UV ink hardly volatilizes organic solvents during the curing process, reducing VOC (volatile organic compound) emissions and meeting environmental protection requirements.

• High printing quality: The cured ink is bright in color, high in gloss, strong in wear resistance and corrosion resistance, and can well present fine graphics and texts.

• Strong adhesion: The ink can form a good bond with the surface of the substrate and is not easy to fall off.

Application areas

• Packaging printing: commonly used for printing various packaging boxes, labels, etc., which can improve the beauty and durability of packaging.

• Advertising printing: can print posters, light boxes and other advertising materials, with excellent color performance, which can attract consumers’ attention.

• Printing of electronic and electrical products: such as logos and patterns printed on the shells of mobile phones, computers and other products. The cured ink can withstand friction and wear in daily use.

• Book printing: some high-end book covers and inserts will use UV printing to enhance the visual effect.
