Pantone Colour: An industry-wide recognised colour that is pre-mixed.

1 Colour Printing: Printing in either black, cyan, magenta, yellow or a pantone colour.

2 Colour Printing: Printing in any two colours (or a mix of any two colours) out of black, cyan, magenta, yellow or any 2 pantone colours.

3 Colour Printing: Usually printing in Cyan, Magenta and Yellow, or the same as for 2 colour printing except with one extra colour.

4 Colour Printing: Usually printing in Cyan, Magenta, Yellow and Black, or any mix of these colours or any 4 pantone colours.

5 Colour Printing: Printing in Cyan, Magenta, Yellow, Black and White (usually used for CD or DVD printing where the disc surface is not white and so the white has to be added).

6 Colour Printing (or more): As for 5 colour printing, but special colours can be added such as silver and gold.

1/0: 1 colour printing on one side of the paper, nothing printed on the other side.

4/0: 4 colour printing on one side of the paper, nothing printed on the other side.

4/1: 4 colour printing on one side of the paper, 1 colour printing on the other side (e.g. a photographic image on the outside of the booklet and black text printed on the inside).

4/4: 4 colour printing on both sides of the paper.

For example, a 4 page booklet printed 4/0 is really a 2 page booklet as only the outside pages will be printed – the insides will be left blank.
