Spot UV Finishes (Spot UV Varnish Packaging)

Spot UV Coating is a carry over term that is used in plastic bag printing to refer to areas of gloss coating on a otherwise standard bag. 


The Spot UV Process used to create these "spot" areas of gloss is different when printing plastics when compared to papers. 

The default finish of most plastics (with a few exceptions) is gloss. The glossy finish of plastics is one of the reasons they are pretty difficult to print. 

With paper, a spot varnish is applied to select area and then cured with Ultraviolet light. But with most flexible plastics printing the process is a bit different.
