Though normally produced in sheet form, by interlacing simple images or different colors throughout the artwork, lenticular images can also be created in roll form with 3D effects or multi-color changes.
If more (30+) images are used, taken in a sequence, one can even show a short animation sequence of about one second. The combined lenticular print will show two or more different images simply by changing the angle from which the print is viewed. Ghosting also occurs on choosing the wrong set of images for flip. When printing to the backside of the lens, the critical registration of the fine "slices" of interlaced images must be absolutely correct during the lithographic or screen printing process or else "ghosting" and poor imagery might result. Once the various images are collected, they are flattened into individual, different frame files, and then digitally combined into a single final file in a process called interlacing.įrom there the interlaced image can be printed directly to the back (smooth side) of the lens, or it can be printed to a substrate (ideally a synthetic paper) and laminated to the lens. This process can be used to create various frames of animation (for a motion effect), offsetting the various layers at different increments (for a 3D effect), or simply to show a set of alternate images which may appear to transform into each other. Lenticular printing is a multi-step process which consists of creating a lenticular image from at least two images, and combining it with a lenticular lens.
