Abstract

A process for applying an energy-curable primer and a brilliant metallic ink to a paperboard or paper substrate is provided. The primer may be cured using an energy curing system such as a UV or EB curing system. The curable primer facilitates the orientation of the metallic pigment particles to provide a coherent reflectance of light and optimal reflectance. Advantageously, the primer-cured paper may be “spot-coated” with the metallic ink at pre-designated areas, which minimizes the amount of metallic ink used. In exemplary embodiments, the metallic paper is over-coated with one or more transparent or opaque inks Additionally, the cured, primer coated paper may be subjected to corona discharge to remove excess solvent and compounds in the liquid phase within the matrix of the cured primer and/or to increase the surface tension of the primer. In certain circumstances, the metallic paper and the end product are recyclable and repulpable.
