Four colour process printing

Many of you will already be familiar with the term 4 colour process printing. Which simply means that four plates are used during printing - one for each of the four process colours; cyan, magenta, yellow and black which are more commonly known as CMYK. Printers also use the terms 4/4, 4/1 and 4/0 but what do these actually mean?

So what is 4/4?

This refers to the number of colours printed on each side of the sheet. It tells us that 4 colours are to be printed on both sides. Usually they will be 4 process colours.

What is 4/1?

Again, this tells us that 4 colours are to be printed on one side and one colour on the other. Usually it will be 4 process colours on one side and black on the other.

What is 4/0?

I’m sure you already worked out that this is 4 colours printed on one side and the other is blank.
