A method for determining the optimal colorant thicknesses and linear combinations for integral illuminant-weighted CIE color-matching filters is provided. A reflectance colorimeter for configuring printers may be designed using this method.

Method for designing a colorimeter having integral illuminant-weighted CIE color-matching filters

A tristimulus colorimeter for measuring reflective or transmissive materials is provided. The colorimeter measures a sample under a calibrated light source, receives inputs to detectors, and determines CIE tristimulus values of the same sample as they would occur under a reference light source. The colorimeter includes a calibrated light source and a single silicon chip that includes three or more detectors. Each detector is permanently coated by a different mix of dyes or other colorants that form a wavelength-selective filter. A single silicon chip embodies all the detectors and electronics, with each detector coated over by deposited filter layers.
