Spot UV varnish
Covering selected surfaces with spot UV curing varnish.
When applied to a matt surface, the selected elements such as the logo, graphics, name, etc. are shiny and nicely highlighted. You can also create new graphic elements visible at the right angle to enrich the design. Thanks to this you can apply varnished backgrounds, "watermarks", patterns, textures, etc.
You can't always get good results. Especially when the UV varnish is applied on very absorbent and "rough" papers without prior printing, it may turn out that the varnish has time to absorb into the paper before it cures, which results in the fact that the coated surface is not uniformly shiny.
