Foiled by Foil

If hot stamping is the process of choice, Richard Zeller, of ITW Foilmark, recommended a few other options. First of all, he said, printers and converters can lay a primer coat over the foil, which increases the surface energy of the foil, allowing for greater adhesion of the UV inks and coatings.

Secondly, using foils specifically designed for overprinting will help, too. These foils "provide a high surface energy that will provide a print-receptive surface," he said.
