Have you ever walked by a display in a store and noticed that the image changes as you walk by it? Or maybe you have picked up a DVD and found that the cover has a serious 3D effect. Chances are that you have seen this special effect printing on occasion for years but didnât know what it was called. While most people come up with the word âhologramâ for any 3D image, these were all likely examples of a special print process called âlenticular printing.â
