Lenticular printing is a technology in which a lenticular lens is used to produce images with an illusion of depth, or the ability to change or move as the image is viewed from different angles. Examples of lenticular printing include prizes given in Cracker Jack snack boxes that showed flip and animation effects such as winking eyes, and modern airport advertising graphics that change their message depending on the viewing angle… Recent advances in large-format presses have allowed for oversized lenses to be used in lithographic lenticular printing.
Adobe evangelist Russell Brown has gotten really excited about using Photoshop to enable creation of lenticular prints, and he’s posted a great set of tutorials and sample files to help get you up to speed. Even better, he’s used the forthcoming Configurator utility to create a panel (see screenshot) that walks you through the steps and actually executes them on demand, right within Photoshop. Super cool.
