What is lenticular?
Lenticular 3D graphics is the combination of two or more images viewed with a special lens to create a desired animated or 3D effect. Images are interlaced or combined, and then placed under a specially designed lens to create dimension and/or motion by allowing the eye to simultaneously view alternating sections of multiple images.
Due to the optics of the lens, the eye is forced to see only a very small area of the image at a certain viewing angle. As you or the printed piece moves, the viewing angle changes and the lens reveals other areas of the image, achieving the transformation effect.
How does lenticular work?
Lenticular graphics are made up of two basic components: a lenticular lens and a flat printed image. The lens is a sheet of plastic material comprised of many grooves and ridges (lenticules) which work to focus your sight on different parts of the underlying image. The underlying image is made up of multiple images which are printed in alternating lines. A narrow band of each individual image will be printed sequentially, and the effect is realized when it is mounted to the lenticular lens specifically chosen to maximize the desired effect.
