RGB stands for “Red, Green, Blue”, and is the primary colours of light. Whenever you’re looking at an image on a screen (computer, smartphone, television, etc) you are viewing it in RGB.
When submitting artwork for print, it is okay to provide RGB images, as they will be converted to CMYK (see below) when printed. Please note however that the colours may shift between what you see on screen and was appears on paper.
CMYK “Process” Colours:
CMYK stands for “Cyan, Magenta, Yellow, Black (or ‘Key’)”, and is the standard used on all offset and digital colour printers. Graphics are created by printing each colour over top of each other to create a composite colour image.
CMYK is generally used when dealing with full-colour images like photographs and colour layouts.
Pantone “Spot” Colours:
Instead of combining colours via CMYK to create a composite image, a “spot” colour is a solid ink colour that is pre-mixed before printing. The press operator will match the colour to the Pantone Matching System, to ensure colour accuracy.
Pantone is an international standard, and this ensure that ANY printer using Pantone’s system can accurately recreate the colour required. Spot colours are generally used for things like logos and branding; solid colours that require consistency and accuracy. Spot colours can also be used in conjunction with CMYK colours when combining full colour images with branding/logo colours on a single layout.
Digital presses are unable to print pre-mixed spot colours, however most spots can be recreated almost exactly using CMYK.
