The CMY colour model deals with a subtractive method of colour mixing. It can be used to explain and provide practical methods of combining three transparent inks and filters (cyan, magenta and yellow) to produce a wide range of other colours and particularly to produce realistic effects when printing digital images onto highly reflective white paper.
- The primary colours in the CMY colour model are cyan, magenta and yellow.
- The CMY colour model is a subtractive colour model used with transparent or translucent inks or filters.
- Meanwhile, the CMYK colour model (sometimes called four-colour or process printing) uses the same three primary colours as CMY but uses a fourth component, black ink (K), to increase the density of darker colours and blacks.
- The CMYK colour model along with its system of notation enables an exact and reproducible approach to colour printing and other similar applications.
- The CMYK colour model is deeply embedded in all contemporary digital printer technologies and underpins industrial standards for the printing industry.
