Pantone Matching System, or PMS, charts include Pantone Color Bridge, Pantone Color Guide and CMYK Guide. According the Pantone, these charts are used by graphic designers, as well as printers who are required to match client-specific colors.
Pantone states that the Pantone Formula Guide offers 1,755 color options for both coated and uncoated print stock. Benefits of the Pantone Matching System include global color recognition, a large selection of popular colors, and the elimination of guesswork where color is concerned. Pantone provides a lighting conditions indicator with the Pantone Formula Guide, helping designers see how a color translates in various lighting conditions.
