Patent ID: 7002748

Claim:
A method of producing a package from a lenticular sheet having anisotropic optical properties comprising the steps of: providing a substrate of transparent material having a first side and a second side and an index of refraction greater than one; forming at least one lens pattern having a plurality of lenses on the first side of the substrate in pre-selected portions thereof, wherein a desired optical effect is produced in the pre-selected portions only; and forming a pre-determined package design from the substrate; wherein the remainder of the first side of the substrate is unaltered, wherein the step of forming the at least one lens pattern further comprises the steps of: engraving a plate or cylinder with a desired lens pattern; removing undesired portions of the lens pattern from the plate or cylinder using a gravure engraving process; and using the resulting plate or cylinder in an extrusion embossment process such that the substrate can be embossed with the remaining lens pattern.
