Patent ID: 7258900

Claim:
A method of printing an image on a document, the method comprising steps of: applying magnetic color-shifting pigment flakes in a fluid carrier to form the image on a surface of a substrate, wherein the step of applying the magnetic color-shifting pigment flakes includes steps of mechanically aligning the magnetic color-shifting pigment flakes to the plane of the surface of the substrate during a first portion of the step of applying, and then de-planarizing at least a portion of the mechanically aligned magnetic color-shifting pigment flakes during a second portion of the step of applying; applying a substantially parallel magnetic field across the image between separate spaced magnets spanning the image or a portion thereof to more closely align at least a portion of the magnetic color-shifting pigment flakes to the surface of the substrate to enhance an aggregate visual effect of the image; and fixing the alignment of the magnetic color-shifting pigment flakes.
