Reverse varnish is divided into forward and reverse directions. In the forward and reverse directions, the full version of the UV oil is applied first, then the UV lamp, and then the local varnish. The particle size can be adjusted by the anilox roller and the UV lamp. In the reverse direction, the local varnish is applied first, and then the full version of the varnish is applied after the UV lamp. The particle thickness can be adjusted by adjusting the amount of local optical ink and the UV lamp. UV reverse varnish is a surface treatment process material that is cured by ultraviolet light. It consists of high gloss reverse UV surface oil and UV ink base oil. The application of UV reverse varnish is a new process of printing and packaging.
