CMYK colour mode


Our offset and digital output are a process-colour (or full-colour) printer. We print CMYK. These are the inks used in process-colour printing – Cyan (C), Magenta (M), Yellow (Y) and Black (K=key).

There are a few product exceptions to this including: Screen-printing, Letterpress, T-Shirts and Rubber Stamps that have a different production process.

It is important when designing your files to use the correct colour mode. CMYK colour mode will give you the closest representation of print output on-screen.

We accept artwork in both CMYK and RGB colour mode – however we recommend supplying artwork and files in CMYK mode so you have more control over the colour and can make any adjustments to the colours.

Files supplied in RGB colour mode will be converted to CMYK colour mode before printing. Some colour shift can occur when converting from RGB colour mode to CMYK – as different software can generate different conversions. We suggest that you or your designer makes the conversion to CMYK so they have control over the colour values.


Certain colours displayed in RGB cannot be produced with CMYK printing (especially bright greens), and black colours will not be optimised for printing if produced in RGB mode. RGB colour mode is a light/screen (additive) display mode. Your screen uses red, green and blue to display colours using light. Some applications (such as Microsoft Word) do not offer support for CMYK mode.

If you are supplying design files in RGB mode we strongly recommend placing your order with Proofing Type as “Online PDF Proof”. A PDF proof will be sent to you for approval before we print, with the colours converted to CMYK colour mode for you to preview.
