ABSTRACT:
A system for determining, in real time, the precise color measurements of a colorant being applied in a printing apparatus, the colorant being a combination of two or more primary colorants. Light from a light source is transmitted through or reflected from the colorant mixture, and received by a sensor having a relatively small number of photodetectors, each photodetector having a different translucent primary-color filter thereon. Various special algorithms can be used to approach the accuracy of a spectrophotometer using a relatively simple light sensor.
