What is UV pad printing ink?

UV printing is a printing process that uses ultraviolet rays to dry and cure ink. It is necessary to use ink containing photosensitizer in conjunction with UV curing lamp. The application of UV printing is one of the most important contents in the printing industry. UV ink has covered offset printing, screen printing, inkjet printing, pad printing and other fields. In the traditional printing industry, UV refers to the printing effect process, that is, a layer of varnish (bright, matte, inlaid crystal, onion powder, etc. ) wrapped in a printed pattern, mainly to increase the brightness and artistic effect of the product and protect the surface of the product, and it has high hardness, corrosion resistance, large friction and is not easy to scratch. Some laminated products are now changed to UV. However, UV products are not easy to stick, and some can only be solved by local UV or polishing. At present, multi-unit glazing unit has become the most basic part of sheet-fed offset press, through which special effects can be easily achieved, and some special materials are often used in cosmetic packaging. Metal paperboard, composite paperboard, aluminized paperboard and glazed paperboard are more and more widely used in the field of cosmetic packaging, showing a sustained and stable growth momentum. New transparent composite materials have also been used in plastic box packaging. Because these substrates can't be printed by ordinary means, the expected effect can only be achieved through UV technology, so not only more and more UV glazing is used, but also the use of UV ink is more common.

According to this trend, UV printing will become the standard configuration in the future, and the printing work with stable quality will no longer rely on luck as before. Powerful paper receiving curing system is only the most basic configuration, and intermediate unit curing is no longer a luxury equipment. These devices provide a broad application space for printing enterprises, and can completely meet various special requirements of the cosmetics industry. UV printing technology mainly refers to the use of special UV ink to achieve partial or overall UV printing effect on UV printer. It is mainly suitable for printing non-absorbent materials, such as the gold card paper, silver cardboard, pearl paper, transparent adhesive, plastic, PVC, PE, grating and so on.
