Abstract
Color image reproduction apparatus includes a video monitor for displaying a reproduced image (a soft copy). A film writer serves to produce a hard copy of the reproduced image on any of a variety of image-receptive output media (reversal film or negative film to print material or reversal film to print material) having perceptually distinct color reproduction properties. 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 film writer to expose an output film (reversal or negative) such that the hard copy reproduction formed is visually matched to the soft copy proof, regardless of the output medium selected.
