Lenticular printing

Lenticular printing is a multi-step process consisting of creating a lenticular image, usually as a layered Photoshop file, creating various frames of animation (for a motion effect) or offsetting the various layers at different increments (for a 3d effect), flattening the elements into individual frame files, and then digitally combining those different frame files into one final file in a process called interlacing. From there the interlaced image can be printed directly to the back (smooth side) of the lens (this is the ideal method) or it can be printed to a substrate (ideally a synthetic paper) and laminated to the lens. The combined effect can be used to show two or more different images simply by changing the angle one views the print from. By increasing the number of images and taking them in a sequence (30+), one can even show a short video of about one second. Alternatively, one can use several images of the same object from slightly different angles and then create a lenticular print, which will then result in a three-dimensional effect. 3D effects can only be achieved in a side to side (left to right) direction, as your left eye needs to be seeing a slightly diiferent angle as your right to achieve the stereoscopic effect. Other effects, like morphs, motion, zooms work better (less ghosting or latent effects) as top-to-bottom effects but can be achieved in both directions.
