The Four Color Printing Process

Four color process printing is a system where a color image is separated into 4 different color values (called a color separation) by the use of filters and screens. This used to be done with photographic film on a graphic arts camera, but is mostly done digitally now. The result is a color separation of 4 images that when transferred to printing plates and sequentially printed on a printing press with the colored inks cyan (blue), magenta (red), yellow and black (the k in cmyk), reproduces the original color image. Most of the entire spectrum or gamut of colors are reproduced with just the four process ink colors. The four color printing process is universally used in the graphic arts and commercial printing industry for the reproduction of color images and text.

The use of color in print increases readership and information retention.

Studies in a major publication revealed that the use of color increased readership by 40% or more. A university study showed a 65% increase in the retention of material when full color was used instead of black and white.
