Rich Black vs. Plain Black

Rich black is an ink mixture of solid black, 100% K, with additional CMY ink values. This results in a darker tone than black ink alone. If you print black alone as 100% K, the resulting black may not be as dark as you might like.

We recommend using
C 60 M 40 Y 40 K 100

This will give you a deep, dark, rich black.

We do not recommend using CMYK values higher than these. Using too much ink will cause the final print to be muddy, and will have a higher chance of smearing.
