Color mixing system

摘要

A method of proportions of toner particles of different colors to be used in a mixture for toning an electrostatic image, the method comprising:determining a desired color for viewing;determining an illumination under which the desired color is to be viewed;determining a target color for printing which results in the desired color being perceived under the illumination;determining a plurality of sets each consisting of only two available candidate toner particles and optionally black and/or transparent color particles;computing a mixture of toner particles of a set of candidate color to particles only from said plurality of sets that best matches target color, according to a predetermined criteria; andmixing the colored toner particles to form a toner for printing.
