PMS color, which stands for Pantone matching system colors, is often used in the printing industry to print spot colors, which are each printed with their own ink. Colors are specified by referring to a Pantone name or number on a color chart. This helps colors appear as they should when they are printed, as opposed to how they may appear when displayed on a computer. Process color is also known as CMYK color. The abbreviations stand for the four colors used, which are cyan, magenta, yellow and black. Together, these are used to create all other colors in the printing process, through the use of different color saturation. This type of color printing is among the most common in the industry.
