Abstract Lenticular printing is widely used for outdoor advertisements, giant posters, and stage backgrounds. Current lenticular printing technology has a number of limitations, including a small number of viewpoints, serious crosstalk among viewpoints, and weak stereoscopic perception. In this study, we developed low-crosstalk super multi-view lenticular printing using triplet lenticular lens. Based on the super multi-view vision principle and the optical transmission characteristics of the cylindrical lens, the optical formula of the lenticular lens were derived. The viewing distance is 6 m, the viewing zone length is 3 m, and the number of viewpoints is 59. According to the above viewing requirements, the parameters of the lenticular lens were designed, including the radius of the curvature, and the thickness and the pitch. The light intensity distributions of 59 viewpoints in the viewing zone were simulated using optical software (Zemax and LightTools). The viewpoint width is 50 mm, which is less than a normal adults’ pupillary distance. Triplet cylindrical lenses were arranged in a circular arc to reduce crosstalk among viewpoints; the crosstalk of 59 viewpoints is from 3.9% to 4.8%. Finally, simulation results were verified experimentally. The results show that super multi-view lenticular printing can meet the requirements of auto-stereoscopic perception.
