Free Knowledge – What are Colour Bars?

Colour Bars are placed beyond the bleed area to allow the printer to control the colour on the printed page.

Colour Bars not only provide a constant stable standard for measuring the flow of various colours used in a printed image over the duration of a print run, they measure the visual properties of ink as well as the performance properties of the printing press. They also provide information for comparing a colour proof to the printed version.
