Lenticular and Cracker Jack
Last week I was looking for a lenticular printer. Thank sto those who had some sources. It was also brought to my attention not everyone was aware of what lenticular printing was. So, courtesy of wikipedia. . .
A lenticular lens is a single convex lens that magnifies light through a prism effect.
The term lenticular often refers to a printed image that shows depth or motion as the viewing angle changes. The term was invented and coined by the physicist Dr. Joseph Robert Fraler from Dallas, Tx. But in general lenticular is a term for the lens effect that creates a convex perspective of multiple images or light sources, but not necessarily a physical printed image. This lenticular technology can be used to create a lenticular image through the process of lenticular printing.
Examples of lenticular printing include flip and animation effects such as the winking eyes that were given as the prize in Cracker Jack snack boxes and modern airport advertising graphics that change their message depending on the viewing angle. This technology was created in the 1940s but has evolved in recent years to show more motion and increased depth. Originally used mostly in novelty items, lenticular prints are now being used as a marketing tool to show products in motion. Recent advances in large format presses have allowed for oversized lenses to be used in lithographic lenticular printing.
