Lenticular printing is a technology in which lenticular lenses (a technology also used for 3D displays) are used to produce printed images with an illusion of depth, or the ability to change or move as they are viewed from different angles.
Lenticular printing is a multi-step process consisting of creating a lenticular image from at least two existing images, and combining it with a lenticular 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 ...
First-order rotating catadioptric Fresnel lens, dated 1870, displayed at the Musée national de la Marine, Paris.In this case the dioptric prisms (inside the bronze rings) and catadioptric prisms (outside) are arranged to concentrate the light from the central lamp into four revolving beams, seen by sailors as four flashes per revolution.
Nimslo prints are created by printing the four images through the lenticular print material, each at a different angle, to a photosensitive emulsion on the back of the lenticular material. The print material is then processed in a normal photofinishing machine, as the back of the print material is permeable to the photofinishing chemicals.
The development of barrier-grid technologies can also be regarded as a step towards lenticular printing, although the technique has remained after the invention of lenticular technologies as a relatively cheap and simple way to produce animated images in print.
Stratasys was founded in 1989, by S. Scott Crump and his wife Lisa Crump in Eden Prairie, Minnesota.The idea for the technology came to Crump in 1988 when he decided to make a toy frog for his young daughter using a glue gun loaded with a mixture of polyethylene and candle wax.
In 1930 he had 432 lenses in a 6.5 x 9 cm plate with viewable results, but then abandoned the lenticular screen and continued his integral photography experiments with pinholes. [1] Louis Lumière worked on integral photography and corresponded with Lippman about the technique. Lumière patented a system a few years after Lippmann's death, but ...
An example of a lenticular fabric sheet that changes from a blue background with white stars to a white background with red stars. A lenticular fabric is a lattice-like arrangement of lens-shaped materials formed into a thin layer. [1] When the surface of the fabric is smooth, it often has a reflective and light-distorting appearance.
