Method of printing a fluorescent image superimposed on a color image

A method of printing a fluorescent image superimposed on a color image such that only an outline of the color image fluoresces to enhance visibility of the color image when the color image is viewed in a dark viewing area, comprising the steps of:

• (a) selecting a dye carrier carrying a plurality of dye color patches thereon, the dye color patches being a yellow dye color patch, a magenta dye color patch, a cyan dye color patch and a phosphorous dye color patch;
• (b) selectively energizing a plurality of heating elements to sequentially transfer a dye from each of the yellow, magenta and cyan dye color patches to a receiver, whereby the yellow, magenta and cyan dye color patches respectively form a plurality of monochrome images that when superimposed in registration one on the other define a color image on the receiver after dyes therefrom sequentially transfer to the receiver;
• and
• (c) selectively energizing the plurality of heating elements to transfer a phosphorous dye from the phosphorous dye color patch to the receiver according to a selected one of the monochrome images, whereby the phosphorous dye color patch defines an outline of the color image on the receiver as phosphorous dye therefrom transfers to the receiver in registration with the selected one of the monochrome images and whereby an outline of the color image fluoresces when the color image is viewed in a dark area.

A method of printing a fluorescent image superimposed on a color image such that only an outline of the color image fluoresces to enhance visibility of the color image when the color image is viewed in a dark viewing area, comprising the steps of:

• (a) providing an inkjet printer having a plurality of channels respectively containing a cyan ink, a magenta ink, a yellow ink, an optional black ink and a phosphorous colorant;
• (b) selectively activating the plurality of the channels to sequentially transfer the cyan, magenta and yellow inks to a receiver, whereby the cyan, magenta and yellow inks respectively form a plurality of monochrome images that when superimposed in registration one on the other define a color image on the receiver after the cyan, magenta and yellow inks sequentially transfer to the receiver;
• and
• (c) selectively activating the plurality of channels to transfer a phosphorous colorant to the receiver according to a selected one of the monochrome images, whereby the phosphorous colorant defines an outline of the color image on the receiver as the phosphorous colorant transfers to the receiver in registration with the selected one of the monochrome images and whereby an outline of the color image fluoresces when the color image is viewed in a dark area.
