Abstract:
A method of producing a quality control device for matching the color, finish or pattern of an item includes determining a plurality of true colors of an item to be matched, the determined colors being anything other than a combination of cyan, magenta, yellow and black. The original product is separated into the plurality of true colors and a random pattern image is generated for each of the plurality of true colors determined. Each of the random pattern images corresponding to each of the true colors generated is transferred onto a printing plate while a plurality of true color inks, correspond in color to the plurality of true colors determined, are provided. The random pattern image transferred to the printing plates is printed onto a substrate, wherein each printing plate prints its corresponding true color ink.
