Lenticular Graphics  
# Tuesday, October 14, 2008

Lenticular graphics come in four flavors: 3D, depth, motion and flip. These visual effects are achieved via a special sheet lens with built-in lenticules. When the lens is placed over interlaced images it separates the images and fools the eye into seeing the a visual effect.

3D lenticular images are similar to a hologram. They offer simulated 3 dimensional imaging. To create a 3D effect photos are taken of the object from different perspectives. The photos are transferred onto the lenticular layers. When viewed from different angles, you see different angles of the object. This creates a very realistic 3D effect.

Depth images are created by layering objects in a file. The lenticular software allows a visual depth to be chosen for each of the layers and the final effect is that of a three dimensional space. Changing viewing angles allows you to see behind objects in the foreground.

Flip graphics bounce visually between several different images. Two or three images are usually all that are used for this effect. These are the original lenticulars, like the old Crackerjack promotions from the 40s.

Motion graphic images are a sophisticated version of the flip. They appear to show an object in motion, like a short video clip. This requires a series of 30 or more images to show the motion.

To create the interlaced images used in lenticular graphics, special lenticular software is needed which can slice up and combine images in a number of interesting ways. Different lenticular lenses with different numbers and thicknesses of lenticules are used to create the various effects.
