  What are the best values of black in CMYK?

When you print with digital presses, as we do, using 100% black is perfect for text but not for large, solid areas. To achieve a nice rich black, we recommend using the formula of 40% cyan, 20% magenta, 20% yellow and 100% black which will give you a great result.

  Why do I need to supply CMYK artwork?

The RGB colour spectrum is much larger than CMYK, and if you supply artwork as RGB, what you receive when printed will differ to what you supplied. Bright colours will appear duller. Before you save your PDF file make sure you have converted it to CMYK so you will have a true indication of what it will look like when printed. You can use Photoshop or to readjust colour if required.

  What’s the difference between CMYK & RGB images?

RGB is the colour gamut used to display images on computer screen, and stands for Red, Green and Blue. CMYK is the colours gamut used for conventional printing, and stands for Cyan, Magenta, Yellow and Black.
