When using large areas of black on a C,M,Y,K page, add percentages of C,M,Y to the black to give the final print a rich appearance.
Note: Listed CMY values are intended for gloss coated sheets #60 or higher. For CMY values for lighter stocks, please contact technical support.
IMPORTANT: Do NOT use rich black for editorial text. Use of rich black should be limited to text in very large point sizes or large solid bars or boxes in your layout.
