The Pantone Matching System or PMS is a standardized color matching and reproduction system that was developed by Pantone Inc. in 1963. The pantone formula guide is the primary tool in a PMS. This guide helped the graphic designers to communicate with printers using a unique Pantone number that was assigned to each color. Using this standardized color system, companies in different locations could communicate with their clients referring to the Pantone system and make sure that their colors match. Now the PMS features around 1,341 Pantone solid colors. These colors are printed on matte, coated, and uncoated papers. The PMS system is also used by software developers for designing purposes. One of the disadvantages of using the PMS is that it does not work well for process colors. The system is best suited for spot colors.
