Pseudo-embossing is a process that uses the repelling properties of two varnishes, UV OP varnish and UV clear varnish, to create a pseudo-embossing-like unevenness. The Riotone process is a printing method that uses a colorless, transparent ink specially designed for Riotone printing, which hardens under ultraviolet light, on the surface of ordinary printed materials. Both have a rough texture, but Riotone has a rougher texture. Riotone processing is not available for packages.
