Patent ID: 7999823

Claim:
A projection display for reproducing a proofed image intended for printing on a substrate using a set of inks, the display comprising: a converter to receive said proofed image in a print color format and to convert said proofed image from said print color format to a display color format by substantially matching colors of the display color format to colors of the proofed image; a light source to generate and project light of a set of at least three colors having at least three different chromaticities, respectively, said chromaticities being selected to define a viewed color gamut which entirely covers a perceived color gamut of said set of inks when printed on said substrate; a controller to receive said proofed image in said display color format and to produce a light pattern corresponding to said proofed image by selectively controlling the path of the light of said at least three colors, and a correction filter, the spectrum of the correction filter being based on the spectrum of an intended light used to view the proofed image when printed on said substrate.
