Lenticular printing is a technology that creates images with an illusion of depth or the ability to change as the image is viewed from different angles. This is achieved by using a special lens called a lenticule, which is a series of small, cylindrical lenses that are placed over a printed image. The lenticules direct light in various ways, allowing multiple images or animations to be seen depending on the viewer's perspective. This printing technique is commonly used for postcards, advertisements, and packaging, providing an engaging visual experience. Lenticular printing can also be used to create 3D images or to display different images in a sequence, making it a popular choice for creative projects and marketing materials.
