As you know uv ink is a consumable that is specifically designed for printing patterns on uv printer equipment. It has a pigment particle diameter of less than 1 micron, is free of volatile organic solvents, has ultra-low viscosity, and has no irritating odor. It ensures that the uv ink does not clog the nozzle during the jet printing process. UV ink is spray-dry, suitable for printing metal, glass, ceramics and other materials. The cured ink layer has high hardness, strong adhesion, scrub resistance, solvent resistance, high gloss, and strong outdoor weather resistance.
The difference between UV ink and solvent ink
UV inks and weak solvent inks determine their respective application methods and applications due to their inherent properties. Since the UV ink is attached to the substrate, it can be embossed after repeated printing. The weak solvent does not adhere to the surface of the carrier but penetrates into the carrier, so there is no way to print the relief effect. Since many materials in the weak solvent need to be coated when printing, unprinted printing products are easy to fade, while UV ink can be directly used to print many materials without any coating treatment. Simple, convenient and practical.
The UV ink reduces the volatile organic matter that escapes from the solvent-based ink during the heating and drying process, and should be matched with the post-processing equipment for post-treatment. The post-treatment method mainly uses the catalytic oxidation method and the cooling recovery method. UV 100% liquid content, no VOC, so there is no environmental pollution problem. Because of its non-toxic, instant drying, fine ink particles, high concentration, good stability, etc., it has been widely used.
Uv ink can eliminate the hot drying tunnel and oven accumulating volatile organic matter post-processing equipment. Since the ink is not dried by the heating and drying method, the mechanism and the electronic component are not disturbed by the high temperature caused by the heating, and the shrinkage, thermal expansion or warpage of the roll is not caused by the high temperature. Therefore, the current amount of UV ink is increasing at a rate of 10%-20%/year.
