ABSTRACT:
Photoinitiator-free inks and a method of producing printed and varnished surfaces are provided by depositing a base film or printing on a substrate and depositing, wet-on-wet, a protective varnish or top coat after which the multilayers are exposed to an energy source, preferably to electromagnetic radiation, to simultaneously cure the varnish and ink on said substrate.
