Lenticular is a unique printing process that creates the illusion of three dimensions, moving images, morphing images, and images that change instantly from one to another. At the center of the process is the lenticular lens material.

This material is made up of parallel rows of optical lenses that magnify and show to the eye only a small portion of the image printed under it.

In order to control the small slice of the printed image that the lens magnifies and shows to the eye, the images under each row of lens are sliced up and correctly aligned for the lens through a process called interlacing (see image at right).
