Abstract
Color image reproduction apparatus includes a video monitor for displaying a reproduced image (a soft copy) to appear on any of a variety of image-receptive output media (reversal film or negative film to print material or reversal film to print material) in which color of the reproduced image may vary from one type of output medium to another. A computer-based workstation, having a series of look-up tables for transforming imaging data to a variety of monitor-dependent RGB color spaces, enables the video monitor to show a series of displays of the reproduced image with each version of the reproduced image being visually matched to the reproduced image as it would appear on a particular one of the image-receptive output media.
