Pantone Matching System
Pantone Matching System (Pantone, PMS) is a color matching system.
Each Pantone color is identified by it's code. Pantone allows for priting metallic colors (like silver and gold), as well as some other colors that can not be truly reached with CMYK colors (for example orange).
You can use Pantone for your order in your artwork.
