Both manufacturers and printers have evolved to accommodate the application of UV ink with the best methods. Apart from UV ink tattoos, people love to apply them to the skin.

How do UV inks work?
UV inks are just the ink that cures under UV light. The inks comprise solid monomers and oligomers molecules as well as pigment and performance additives. It also contains a substance called photoinitiator, which releases free radicals when exposed to UV light, enabling the molecules to bond together and create a solid ink layer. So, instead, the ink sits on top of the substrate, making it ideal for printing smooth surfaces.
