Rich Black Printing
Rich Black is the solution to black print that looks a little gray or dull. Black that is specified as K 100, C 0, M 0, Y 0 may result in a final color that might not be as dark as expected. Rich Black is 100% black mixed with additional CMY ink values. We recommend using C 60, M 40, Y 40, K 100 to give your print jobs a neutral, deep, and rich black.
