Abstract

An ultraviolet image pattern is created on a recording medium having florescence properties and being a first color by electronically creating a first electronic pattern ink, the first electronic pattern ink including a second color and including holes, the holes representing areas in the first electronic pattern ink wherein the second color is absent; electronically creating an electronic image region having a pattern; electronically painting, using the first electronic pattern ink, a background of the electronic image region and the pattern of the electronic image region; electronically painting a predetermined portion of the holes with a third color, the third color matching the first color of the recording medium; and rendering, using marking materials, the electronic image region on the recording medium such that the florescence properties of the recording medium are only visible through the holes not painted with the third color when viewing the recording medium using ultraviolet illumination.

First claim

What is claimed is:

1. A method for rendering an ultraviolet image pattern on a recording medium having florescence properties and being a first color, comprising:
(a) electronically creating a first electronic pattern ink, said first electronic pattern ink including a second color and including holes, said holes representing areas in said first electronic pattern ink wherein said second color is absent;
(b) electronically creating an electronic image region having a pattern;
(c) electronically painting, using said first electronic pattern ink, a background of said electronic image region and said pattern of said electronic image region;
(d) electronically painting a predetermined portion of said holes with a third color, said third color matching the first color of the recording medium; and
(e) rendering, using marking materials, said electronic image region on the recording medium such that said florescence properties of the recording medium are only visible through said holes not painted with said third color when viewing the recording medium using ultraviolet illumination.

2. The method as claimed in claim 1 , wherein said predetermined portion of said holes painted with said third color are holes within said pattern of said electronic image region.

3. The method as claimed in claim 1 , wherein said predetermined portion of said holes painted with said third color are holes within said background of said electronic image region.

4. A system for rendering an ultraviolet image pattern on a recording medium having florescence properties and being a first color, comprising:
a processor for electronically creating a first electronic pattern ink, said first electronic pattern ink including a second color and including holes, said holes representing areas in said first electronic pattern ink wherein said second color is absent; and
said processor electronically creating an electronic image region having a pattern;
said processor electronically painting, using said first electronic pattern ink, a background of said electronic image region and said pattern of said electronic image region;
said processor electronically painting a predetermined portion of said holes with a third color, said third color matching the first color of the recording medium; and
a print engine for rendering, using marking materials, said electronic image region on the recording medium such that said florescence properties of the recording medium are only visible through said holes not painted with said third color when viewing the recording medium using ultraviolet illumination.

5. The system as claimed in claim 4 , wherein said predetermined portion of said holes painted with said third color are holes within said pattern of said electronic image region.

6. The system as claimed in claim 4 , wherein said predetermined portion of said holes painted with said third color are holes within said background of said electronic image region.
