Abstract

A device, system and a method for soft proofing of an image before it is printed onto printed material, such that the colors of the image substantially reproduce, to the human eye, the colors as they should appear on the printed material.

Claims

1. In a device for soft proofing image data for printing, the device comprising a light source for producing light having at least four primary colors, a converter for converting the image data to a proportion of at least one of said at least four primary colors according to at least one characteristic of the printed material to form converted data, and a viewing screen for displaying the image according to the converted data, a method for creating the image for displaying, the method comprising the steps of:

(a) determining at least one characteristic of the printed material according to at least one of a spectrum of a set of inks and a color reflection characteristic of a material for receiving said set of inks;

(b) producing light by the light source of at least four primary colors;

(c) determining a path for light of each primary color according to the converted data; and

(d) projecting said light of each primary color according to said path onto the viewing screen to form the image.

2. A method for soft proofing image data of a plurality of colors for printing to form printed material, comprising the steps of:

(a) providing a color system for printing the printed material, said color system featuring a plurality of colored materials, each colored material being subtractive, such that said colored material has a color by blocking at least a portion of a spectrum of light impinging on said colored material;

(b) producing light of at least four colors for electronically displaying the image data;

(c) combining light of a plurality of said colors to reproduce each color of each colored material for electronically displaying the image data, said light of said plurality of colors being combined additively to form a combination; and

(d) displaying the image data with said combination of said light of said plurality of colors.

3. The method of claim 2, wherein each color of said light is substantially spectrally matched to each color of said colored materials.

4. The method of claim 2, wherein step (b) is performed with a projective light system, said projective light system featuring a light source for producing said light of at least four colors, and a viewing screen for receiving said light for displaying the image.
