RGB VS CMYK

RGB denotes the colours red, green and blue and is primarily used for digital displays. Monitor pixels have three light units red, green and blue which dictates the colours used in this colour production method. The luminosity of the light units is set and the colours are applied to the pixels.  It is an additive process using primary colours which are combined to create a full spectrum of colours on a screen, with white being at the lowest extent and black being at the highest. It is used in photo editing as it has the greatest range of colours making it more vivid and vibrant.

CMYK is a four-colour mode used for digital printing. Cyan, magenta yellow and black are used in combination in varying amounts to create all the necessary colours. It is a subtractive process that involves the layering of ink to remove light to produce a colour. When all three are combined they do not create black, instead it is a dark brown. The removal of light from the page in these areas means it is perceived as black. CMYK printing does not include white as there is an assumption that the work is printed on white paper. The combination of white and the percentage of each colour used will determine how dark a colour will be. 

When converting RGB to CMYK it will print much darker and duller than on screen. CMYK will always print as it is seen on screen, whereas RGB may not.
