What is overprinting?
Overprinting allows new colors to be created by the intersection and overlay of two or more separate colors. By carefully planning the design of a printed piece, overprinting can yield more colors than suggested by the required number of print runs. For example, in a finished piece printed in red and yellow (which would require two setups and two individual plates), overprinting selected areas of the image would result in a third color, orange—without having a separate plate and print run for the orange areas.
