ABSTRACT:
A method and apparatus for reproducing both pictorial image information and text information on a sheet or surface used in the production of a printed page. The original image is scanned at a low resolution to produce density values for each color separation. The original image is then scanned at a second higher resolution to derive signals representative of the density values for the black separation. Scanned data for each color separation is stored and then interpolated to the second higher resolution prior to being printed and the data associated with the black separation is then printed at its original resolution by the printer.
