ABSTRACT:
Multiple electroluminescent (EL) emitters are constructed from layers deposited on a substrate and incorporated with a broadband sensor to form a colorimeter. The EL emitters produce light covering spectral segments determined by a filter layer and an active layer wherein the spectral segments sufficiently cover the visible spectrum to enable a wide range of colors to be accurately measured. The colorimeter is mounted in a desktop color printer to measure the color content of printed images and to calibrate the printer.
