Abstract
A method of printing a fluorescent image superimposed on a color image. An image source captures an image and converts the image to an image file that is transferred to a controller. The controller controls operation of a print head that prints a plurality of monochrome images forming a color image when the monochrome images are superimposed in registration one upon the other. In the case of a thermal dye printer, the plurality of monochrome images are formed by selective thermal transfer of dye from yellow, magenta and cyan dye color patches to a receiver. In the case of an inkjet printer, the plurality of monochrome images are formed by selective activation of ink channels containing cyan, magenta and yellow ink so as to eject cyan, magenta and yellow ink droplets onto the receiver. In the case of the thermal dye printer, the invention provides a dye carrier containing a phosphorous dye color patch. In the case of an inkjet printer, the invention provides that at least one of the channels contains a phosphorous colorant. After the color image is formed, using either the thermal dye printer or the ink jet printer, image information defined only by a selected one of the monochrome …
