The lenticular flip effect is a visual technique used in lenticular printing that creates the illusion of two or more distinct images flipping back and forth as the viewing angle changes. This effect is achieved by interlacing multiple images and then printing them beneath a lenticular lens. As the viewer shifts their perspective, the lens directs light from different images to the eyes, resulting in the perception of the images flipping.
Key characteristics of the lenticular flip effect include:
- Multiple Images: The effect typically involves two or more images that alternate as the viewing angle changes [1].
- Interlacing Process: Images are sliced into narrow strips and interlaced in a precise pattern. This interlaced image is then printed on a substrate and covered with a lenticular lens [3].
- Viewing Angle: As the viewer’s perspective shifts, the lenticular lens directs light from different images, creating the flip effect. This makes it possible for one image to be visible from one angle and another image from a different angle [4].
- Applications: The flip effect is commonly used in advertising, packaging, and novelty items to attract attention and engage viewers with dynamic visual content [6].
