The term colour gamut refers to the range of colours that exist within a specified working space. For example RGB has its own working space and range of colours, CMYK has a different working space and range of colours. Not all the colours that exist in the RGB working space exist in CMYK. Neither of these colour ranges can reproduce all colours seen by the human eye. The RGB gamut of computer monitors varies. LCD screens have a much smaller gamut. The term ‘out of gamut’ relates to a range of RGB colours that cannot be reproduced on a CMYK printer. Most packages deal by default with RGB which contains a different range of colours than CMYK. Therefore it is important that you have checked the the colour conversion to check it retains its original appearance (See next question).
