Several different color models are used today. Below is a description of the three most common models for printed materials and the most common used for projected images.
PANTONE Uncoated: This is used for letterhead, the multi-purpose paper used in most printers, envelopes, and most business cards. Colors are selected from the PANTONE Matching System designated as the uncoated model.
PANTONE Coated: The coated model is most often associated with media guides, magazine covers and postcards. There is a glossier look to coated paper as opposed to uncoated. Colors are found in the PANTONE Matching System designated as the coated model.
Process Color: Printing companies use the phrase "four color process"
or CMYK (referring to the four colors - Cyan, Magenta, Yellow, and blacK - used in processing). For programs that do not have PANTONE models, this is the best substitute for printed materials. Colors are broken down into these four parts, and have values ranging from 0 to 100.
RGB "Web" Color: This model is best for projected images; images seen on a television, computer or video screen. In this model, colors are broken down into three components of light: Red, Green, and Blue.
