Lenticular refers to a type of lens that is shaped like a double-convex lens, which means it is thicker in the middle and tapers off at the edges. This design allows it to focus light and create images that can change or appear three-dimensional when viewed from different angles. Lenticular lenses are commonly used in various applications, including 3D displays, posters, and advertising. In addition to their optical uses, lenticular technology is also employed in printing to produce images that shift or animate as the viewer moves. This effect is achieved by layering multiple images behind the lenticular lens, creating a dynamic visual experience. Lenticular printing is popular for creating eye-catching graphics and promotional materials.
