The colour gamut is the range of colours achievable specific to individual devices. All CMYK devices have different colour gamuts. For example, a standard small format laser printer typically contains only 4 inks (cyan, magenta, yellow and black), where as many inkjet printers can contain up to 12 inks, allowing them to achieve a larger colour gamut.
Visible Colours: The human eye has the largest colour gamut.
RGB: RGB devices have the second largest colour gamut
CMYK: CMYK devices have the smallest colour gamut
It is important to understand how to build files and how they will convert to CMYK for digital printing. Coverting colour spaces is not a simple formula.
