Lenticular is an adjective often relating to lenses. Lenticular printing is a technology in which lenticular lenses are used to produce images with an illusion of depth, or the ability to change or move as the image is viewed from different angles.

Lenticular technology has matured and artists who produce lenticular prints today have access to superior imagery more 3D movement and greater colour saturation. A long way for the lenticulars on cereal packets and rulers we remember from childhood.

The technique uses several images which are sliced into strips and interlaced together. A plastic sheet containing a set amount of linear prism-like lenses is then placed on top, perfectly aligned with the images for the 3-dimensional effect to work.

Depending on where the viewer is standing, each lens acts as a magnifying glass to enlarge and display a different portion of the image. The combination of many lenses working together with many interlaced images creates a three-dimensional horizontal image plane when the viewer looks at the image from a different angle from left to right. This is because each eye views the print from a slightly different angle and sees a different image with different perspective views of the subject, giving the 3D stereoscopic effect.
