  • Optical intermediate produced by a calibrated printer for use in an electrophotographic copier to compensate for determinable copier reproduction characteristics
    Patent number: 5181124
    Abstract: An arrangement for producing electrophotographic reproductions of an original image, including a source of digitized data that digitally represents an original image, a photocopier having determinable reproduction characteristics and which produces electrophotographic reproductions, and a printer. The printer is coupled to the source that receives the digitized data and produces an optical intermediate from the digitized data. This optical intermediate compensates for the determinable reproduction characteristics of the photocopier and of the scanner such that photocopying of the optical intermediate by the photocopier produces an accurate electrophotographic reproduction of the original image. The printer is provided with a composite device function table that relates target image pixel values used by the printer to measured color data of the output of the photocopier.
