Lenticular sheets contain images that appear to move or otherwise change, depending on the viewing angle. Each of these sheets consists of a certain amount of lenses, which give the image on the sheet a certain effect. There are various kinds available:

• Flip-flop: the image changes completely.
• 3D effect: the flat image appears to be three dimensional.
• Animation: the image appears to move.
• Zooming: the image appears to come closer/further away.
• Morphing: the image morphs into a slightly different image.
