Abstract:

A method of color design is provided in which multi-color, fast copies of a multi-color optical image, in a multiplicity of color design combinations are obtained. These fast copies enable a designer to quickly possess proofs of his design in various color combinations. The method comprises: A. independently changing and viewing the colors of individual components of a color variable image until a desired color combination of the image is obtained; B. projecting the colored image from (a) onto the input of a multi-color reproduction copier; C. making a copy of the image in a visual match of the colors projected; and D. repeating steps (a), (b), and (c) any desired number of times to obtain fast copies of the image in a multiplicity of color combinations.
