Abstract
A control system (10) for a four-color printing press (11) having a device (21) for detecting the energy reflected from a paper surface in both the visible region and the infrared region of the electromagnetic spectrum, a device (23) for converting the output of the detecting device (21) to a set of variables which represent the amount of ink presented on the paper for any of the cyan, magenta, yellow, and black inks, and a device (25) responsive to the converting device (23) for adjusting the four-color printing press (11) to maintain the color consistency with or without an additional color control target.
