Patent ID: 7773222

Claim:
A full width array spectrophotometer system for full width scanning color analysis of a printed media sheet, comprising: an elongated illumination array of closely spaced illumination sources, comprising: a first set of illumination sources of different colors in the visible range, and a second set of UV-emitting illumination sources comprising at least one UV-emitting illumination source; the sets arranged so as to extend sufficiently in a substantially linear dimension to transversely substantially span a printer paper path to illuminate, with the illumination sources of different colors in the visible range and the UV-emitting illumination source, a transverse illuminated band extending transversely across a printed print media sheet moving in the paper path; and a full width array radiation sensor comprising an elongated array of multiple closely spaced photodetectors for detecting plural colors adjacent to and extending substantially parallel to the at least one substantially linear array of closely spaced multiple illumination sources, the full width array radiation sensor being positioned to receive radiation reflected from the transverse illuminated band extending transversely across the print media sheet moving in the paper path.
