What is Rich Black and when should I use it?

When your project prints, we use 4 color process or CMYK (unless you are printing black and white or with PMS colors).  As each color in the process is laid down over the previous it creates the images and colors you see in your design.

So, what does rich black have to do with 4 color process?  A standard black is made up of just the black ink, the K value in CMYK.  Rich black has a little of the Cyan, Magenta and Yellow in it as well, creating a richer black color.

When printing large areas of solid black on full color projects we recommend you create a “rich black”.  Printing with only 100% black may cause the black ink to look light or washed out.  By printing with a rich black the color will look much richer.

There are different formulations of rich black, but we suggest your rich black color be made up of:  60% Cyan, 20% Magenta, 20% Yellow and 100% black.

Please create this color build, do not select the color “registration” when choosing a black.  Registration black is made up of 100% Cyan, 100% Magenta, 100% Yellow and 100% black, and is generally too much ink!

It is important to only use a rich black for large, solid areas.  Do not attempt to use this for small type.  The difference it not that noticeable since it covers such a small area and it can make registration of the plates very difficult!
