Color-matched printing

Abstract From the Canadian patent

A technique is disclosed for matching a color applicable for example to, printing a color which matches a color on a CRT display. Quantities of toners which will generate the matching color are determined and then a pattern of toners which will approximate those quantities is applied. To determine the quantities, a definition of the original color such as its RGB, coordinates, is converted to coordinates in a linear mixing space such as, CIE coordinates. These coordinates together with coordinates of the, toners are then used to calculate quantities of toners which will produce a matching color. The calculations match hue saturation and reflectance so, that the matching color appears like …
