UV printing is one of the most important contents in the printing industry. It is suitable for printing non-absorbent materials, such as gold cardboard, silver cardboard, pearl paper, transparent stickers, plastics, PVC, PE, gratings, etc.

The advantages of UV:

1. Printing should be good. UV prints have clear dots, good tone reproduction, bright ink colors, and high printing consistency.

2. The UV curing process is a photochemical reaction process, so whether it is an ink layer or a varnish layer, it has the advantages of strong adhesion, strong durability, and water resistance, chemical corrosion resistance, wear resistance, and aging resistance.

3. Three-dimensional patterns can be printed on the surface of the packaging box, which can be printed at one time, without plate making, plate printing and repeated color registration; compared with the traditional four-color process printing, the amount of UV printing ink is wasted.

4. UV ink curing process will not cause more harmful environmental pollution, and less waste, and save energy, belongs to environmental protection ink.
