What are metallic inks?
Metallic inks are basically tinted varnishes with metallic particles. As the ink dries, the metallic particles rise to the surface and start to reflect light. But beware: Depending on the substrate, the shine can cause rub-off. As a rule, the smoother the surface, the less rub-off will occur. A textured paper, for example, is an unstable surface. Just imagine two pages on the inside of a brochure that are printed with metallic inks and now rub against each other—the textured surface reacts like sandpaper.
