1. 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, anda 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.

Abstract
A display (36) for reproducing an image intended for printing on a substrate using a set of inks, the image having a perceived color gamut when print it on the substrate, the display (36) including a light source (38) generating a set of at least three primary color (RGB), and a controller (42) combining the set of at least three primary color to substantially reproduce the image, wherein the at least three primary color define a viewed color gamut which substantially covers the perceived color gamut.

16. A method for reproducing by projection a proofed image intended for printing on a substrate using a set of inks, the method comprising:
-
projecting light 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; receiving said proofed image in a print color format; converting said proofed image from said print color format to a display color format corresponding to said at least three colors by substantially matching colors of the display color format to colors of the proofed image; passing light through a correction filter, the spectrum of the correction filter being based on the spectrum of an intended light source used to view said proofed image when printed on said substrate; and based on said converted proofed image in said display color format, selectively controlling the path of the light of said at least three colors to produce a light pattern corresponding to said proofed image. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
