Professional printers and graphic artists have different definitions of the colours or "hues" they apply when working. The traditional primary colours that painters use are red, yellow, and blue. However, the colours used by printers are magenta, yellow, and cyan. Colour printing devices are unable to reproduce the full range of colours visible to the human eye. Each piece of equipment operates within its own specific colour window, which can display a clear range, or gamut, of colours.
| The RGB (red, green, blue) and CMYK (cyan, magenta, yellow, black) colour modes are the two major categories of colour representation systems. Gamuts in the RGB and CMYK show significant differences; whereas the RGB gamut is usually broader (it can represent more colours) than CMYK. Some CMYK colours are still not covered by the RGB gamut. Differing equipment also produces varying gamuts inside the same colour mode. For instance, varying RGB spaces can be produced by different scannersand monitors, whilst a variety of CMYK spaces can come from different printers. |
| Due to these varying colour spaces, colours can change in appearance as one transfers documents between different devices. Colour variations can come from different image sources (scanners and software produce media using different colour space systems), differences in the way software applications define colour, differences in print media (newsprint reproduces a finer gamut than magazine-grade paper). Technical factors such as manufacturing differences in monitors or monitor age also play a role. |
