Every screen and printer will reproduce colours slightly differently. By standardizing the colours, different manufacturers in different locations can all refer to the Pantone system to make sure colors match as closely as possible. The colour specification is a guide only. The CMYK and RGB breakdown is not a literal translation of the Pantone colour. There can be very drastic differences in color when you choose a Pantone color and then print as four-color process (CMYK). We recommend that you always compare an official Pantone swatch to a CMYK proof, before committing to a print run, so all parties will be aware of possible color shifts.
