1. A specialty ink-jet ink, comprising:
- an ink vehicle; and
a sufficient amount of particulates having directionally dependent light reflective properties dispersed within the ink vehicle such that when the ink-jet ink is substantially dried on a desired substrate, a multi-colored reflected light is emittable in the presence of a light source due to diffraction of light off of the particulates, said specialty ink-jet ink being ink-jettable.

Abstract
The present invention provides ink-jet inks, systems, and methods for marking documents as original. Specifically, an aqueous ink-jet ink can comprise an ink vehicle; and a sufficient amount of particulates having directionally dependent light reflective properties within the ink vehicle such that when the ink-jet ink is substantially dried on a desired substrate, a multi-colored reflected light is emittable in the presence of a light source. Printing documents as original can be carried out for compensation, as a service, or by providing cartridges containing these inks to clients and/or customers.

11. An aqueous inkjet ink printing system, comprising:
-
a specialty ink-jet ink comprising an ink vehicle having dispersed therein an effective amount of particulates, said particulates having directionally dependent light reflective properties due to diffraction of light off of the particulates; and
a specialty ink-jet ink pen configured for jetting the ink-jet ink. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A method for marking a document as an original, comprising:
-
providing an image-containing document that is to be marked as an original; and
ink-jetting a visible mark onto the document, wherein the visible mark has a non-copyable property, said non-copyable property being a directionally dependent light reflective property present in the visible mark when exposed to a light source such that a multi-colored reflected light is emittable in the presence of the light source due to diffraction of light off of particles in the visible mark. - View Dependent Claims (22, 23, 24, 25)
