Description

A kind of UV-curable embossed ink and preparation method thereof

technical field

The invention relates to an ink and a preparation method thereof, in particular to an ultraviolet light curing embossed ink and a preparation method thereof.

Background technique

UV curable embossed ink is a kind of screen printing ink, which can form a colorful embossed effect after being irradiated by ultraviolet lamps with specific wavelengths. This ink can be widely used in high-end packaging, and can be formulated into various colors according to customer requirements. Bright embossed ink with excellent cure speed and adhesion. Existing UV-curable embossed inks require multiple printings to form the embossed effect, which is prone to inaccurate overprinting, time-consuming and material-consuming. the
