The Difference Between UV Ink and Solvent Ink

Apr 15 , 2020

UV Printing Inks is a consumable used exclusively for printing patterns in UV printer equipment. Its pigment particle diameter is less than 1 micron, does not contain volatile organic solvents, ultra-low viscosity, no irritating odor. It can ensure that the UV ink does not block the nozzle during the jet printing process. UV ink is sprayed and dried, 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 weather resistance outdoors.

UV ink and Mild Solvent Ink determine their respective application methods and application fields due to their inherent characteristics. Because 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. Because the ink on the weak solvent needs to be coated for many materials when printing, printed products without coating are easy to fade, and the UV ink can be used to print many materials directly without any coating , Simple, convenient and practical.

The UV ink reduces the volatile organic compounds that the solvent-based ink dissipates during the heating and drying process. It should be equipped with post-processing equipment for printing. The post-processing methods mainly include the catalytic oxidation method and the cooling recovery method. UV100% liquid content, no VOC, so there is no environmental pollution problem. And because it has the advantages of non-toxic, instant drying, fine ink particles, high concentration and good stability, it has been widely used at present.

UV ink can eliminate the need for post-processing equipment for volatile organic compounds in hot ovens and ovens. Because it does not dry the ink by heating and drying, the mechanism and electronic components will not be disturbed by high temperature caused by heating, and at the same time, it will not cause shrinkage, thermal expansion or warpage of the roll due to high temperature. Therefore, the current UV ink usage is increasing at a rate of 10% -20% / year.
