Abstract

Color separations for use in page make-up are produced by scanning an outline original in a color scanner to obtain a first output with high spatial resolution, modifying the output for reception by a video graphic system, generating a second full color range output with lower spatial resolution by use of the manual input means of the system, with reference to a display on the system monitor derived from the first output, combining the first and second outputs to obtain an output with the high spatial resolution and the full color range, and producing the separations by feeding the combined output to the expose side of the color scanner.
