CanSCHOOL Spotlight: Clear Varnish Coating in a Decorator

Right after decoration, cans receive a clear varnish coating for protection and appearance.
A fountain supplies varnish to a gravure roll, which meters and transfers it to a rubber applicator roll.
As cans pass by on the mandrel, they’re coated with a thin, even layer.
This step boosts durability, enhances the visual finish, and helps with smooth conveyance downstream!
