Disclosed herein is a method for producing a lenticular sheet comprising the steps of providing a substrate of transparent material having a first side and a second side; and engraving a cylinder with an inverse lens pattern, the inverse lens pattern being comprised of a plurality if inverse lenticule shapes, each inverse lenticule shape having an incremental pitch relative to the others; and using the engraved cylinder in an extrusion embossment process such that the substrate can be embossed with the inverse lens pattern, wherein the lenticular sheet produced comprises a lens pattern having a plurality of lenticules each of a uniform pitch relative to one another.
