Patent ID: 8167391

Claim:
A method of making edible substrates having consistent registration of images disposed thereon, wherein said method comprises: (a) providing an edible substrate sheet having at least one image disposed thereon; (b) providing a trigger pulse signal, wherein said trigger pulse signal relays the frequency of a process element; (c) communicating the trigger pulse signal to a piezoelectric drop-on-demand ink jet printer, wherein the piezoelectric drop-on-demand ink jet printer uses the trigger pulse signal to determine when to record an image to said edible substrate sheet; (d) communicating a recorded image to an image analyzer, wherein said image analyzer determines whether the edible substrate image meets predetermined criteria; and (e) disposing the recorded image on said edible substrate sheet with said piezoelectric drop-on-demand ink jet printer wherein the edible substrate image meets said predetermined criteria; wherein said edible substrate sheet is a fabricated snack dough sheet wherein said fabricated snack dough sheet comprises a material selected from the group consisting of potato, rice, corn, wheat, and combinations thereof; wherein a camera having a filter lens to increase the contrast between the printed image and the edible substrate sheet is used with a strobe light to produce the recorded image; and wherein said camera and said strobe light are triggered off the same trigger pulse signal used to trigger said printer.
