Abstract
Herein is described a method of applying foil from a foil web to a substrate. The method may comprise: ink-jet printing a UV-curable adhesive onto the substrate in a predetermined image area; subjecting the adhesive to a first curing by exposing the adhesive to UV light in a dosage range of 140-170 mJ/cm2; passing the substrate and a foil web through a nip where the foil web is pressed against the adhesive; subjecting the adhesive disposed between the substrate and the foil web to a second curing by exposing the adhesive to UV light in a dosage of at least 250 mJ/cm2; and separating excess foil from the substrate, to leave foil on the predetermined image area. Substrates and UV-curable adhesives are also described.
