Image registration on edible substrates
A method of making edible substrates that have an image registered on them in a consistent manner. The method comprises the steps of providing an edible substrate sheet, and an image source, wherein the image source has at least one image. Further, a trigger pulse signal is provided, which relays the frequency of a process element that is communicated to an image disposal device. The image disposal device uses the trigger pulse signal to determine when to dispose an image from the image source. Then an image is disposed on the edible substrate sheet with the image disposal device to form an image-disposed edible substrate sheet. And then a portion of the edible substrate sheet that comprises an image is separated into an individual piece.
1. 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.
2. The method of claim 1 , wherein said image analyzer determines whether the actual location of a printed image corresponds with the target location for said printed image.
3. The method of claim 2 , wherein the piezoelectric drop-on-demand ink jet printer is located before a cutter unit and the target location is analyzed in relation to the cutter.
4. The method of claim 2 , wherein the ink jet printer is located after a cutter unit and the target location is analyzed in relation to the outline of the cut piece.
