What is Rich Black?
Rich black is an ink blend of 100% black, plus 40% cyan, 30% magenta and 30% yellow. The result is a solid black that is really black.
Not only does it make large areas of solid black look great, it can make black type that overprints a four-color image much more legible. Rich black is an example of a production technique that invites the eye to take a second look at your printed material. It can make your printed piece stand out and draw the reader into the page.
