Lenticular printing, lenticular printing is a technology for printing images in which a lenticular screen is used to create the illusion of depth and multiple perspectives, or to change the image when viewed from different angles.

Examples of lenticular printing include three-dimensional and animation effects, and in colloquial speech the corresponding types of prints are called "stereo" and "vario". Both effects can be combined in one print. For example, in the USSR, "stereo postcards" printed in this way were popular, on which a three-dimensional portrait winked when the print was slightly tilted. At the same time, children's badges of this type, unofficially called "periluvashki", became widespread. In some countries, such as the United States and Great Britain, lenticular prints are sometimes colloquially referred to as "holograms" due to the similarity in appearance of the resulting effect. However, this technology has nothing to do with buyer will receive exactly the same item as in the photo.
