ABSTRACT:
A selective color copyability illuminator includes a pair of lamps each having a spectral emission suitable for copying black and white documents or documents incorporating a specific color. The lamp emissions are selectively controlled depending upon the color of the document being copied. Faceted reflectors, associated with each lamp, are moved to positions which cover or uncover the lamp aperture to enhance selective deletion of a particular color of the document being copied.
