What is the difference between process and spot colors (PMS colors)?
Process colors are the colors needed for 4-color process printing (Cyan, Magenta, Yellow, and Black: commonly referred to as CMYK). This is a standard printing method employed by printers worldwide to print pieces with color photographs or illustrations. Spot color printing is a technique in which solid ink is applied to a printing surface (as opposed to the CMYK patterned dot method). This is used on projects where special inks (like metallic colors) are part of the color scheme and in circumstances where pure and complete ink coverage is desired. Spot colors are picked from the Pantone Matching System (PMS) pallet, so they are consistent throughout the printing industry. If while creating your design you use spot colors but want us to print using CMYK, there will be a noticeable shift in color.
