How Lenticular (holographic-like) Images Work
Remember those great eye-winking trinkets you'd get from the Cracker Jack box as a kid? Those were very rudimentary forms of lenticular imagery. Lenticular technology, often confused with holograms, has come a long way since those days. We now find lenticular images integrated into packaging, drinkware, movie posters, book, CD and DVD covers, to name a few. You don't have to look very far to find an example. But, would you recognize it as lenticular? Probably not! So, we've assembled this Squidoo lens to educate the world on lenticular.

Lenticular Image Interlacing
Multiple image (frame) files are interlaced (interweaved) into a single lenticular image using specialized software. The interlaced image is finely-tuned (resolution) to the specific characteristics of the lenticular lens, as well as the desired viewing distance.
Lenticular Lens
A lenticular lens is comprised of extruded clear plastic lenticules ("ribs"). Each lenticule works as a magnifying glass, revealing only portions of an interlaced image at a time. The frames of the interlaced image change as the viewer changes viewing angle of the lens.
Three-Dimension (3D) Image Effect
The Three-Dimension effect positions visual elements on different spacial planes. The interaction of these elements create the illusion of depth. The Three-Dimension effect can be used in combination with other effects.Lenticular Lens Orientation: Vertical lens orientation (side-to-side/walk-by motion) is required for the Three-Dimension effect.
Motion Image Effect
The Motion effect plays image frames like a motion picture projector. These short movie clips can be comprised of computer-generated animation, video, time-lapsed photography, and even motion picture film. The Motion effect can be used in combination with other effects.Lenticular Lens Orientation: Horizontal lens orientation (top-to-bottom motion) will provide the best Motion result; however, a vertical lens (side-to-side/walk-by motion) will produce very good Motion results.
Morph Image Effect
The Morph effect dynamically transforms one visual element into another. This effect is a great tool for a retroactive comparison of a new product, logo, or technology. The Morph effect can be used in combination with other effects.Lenticular Lens Orientation: Horizontal lens orientation (top-to-bottom motion) will provide the best Morph result; however, a vertical lens (side-to-side/walk-by motion) will produce very good Morph results.
Flip Image Effect
The Flip effect turns visual elements of an image on and off. One image can completely change to another. This effect is a great tool for "before-and-after" and "cause-and-effect" demonstrations. The Flip effect can be used in combination with other effects.Lenticular Lens Orientation: Horizontal lens orientation (top-to-bottom motion) will provide the best Flip result; however, a vertical lens (side-to-side/walk-by motion) will produce very good Flip results.
Zoom Image Effect
The Zoom effect forces visual elements, or even an entire image, to be propelled forward. This effect is a great tool for focusing attention on a featured product, logo, or marketing message to be conveyed. The Zoom effect can be used in combination with other effects.Lenticular Lens Orientation: Horizontal lens orientation (top-to-bottom motion) will provide the best Zoom result; however, a vertical lens (side-to-side/walk-by motion) will produce very good Zoom results.
Effects Combination
Three-Dimension, Motion, Morph, Flip and Zoom effects can be combined into a single lenticular piece. Effects selection should be based on the specific result to be achieved.Lenticular Lens Orientation: Lens orientation should be based on the specific application of a lenticular piece. A vertical lens is always required for the Three-Dimension effect.
Lenticular Terms
Common terms used in lenticular production.
3D
Lenticular image effect that creates a three-dimensional illusion using multiple images (same as depth).
Alignment
The parallel positioning of a lenticular image to the lenticules (ribs) of the lens.
Animation
Lenticular image effect using multiple images to create the illusion of motion (same as motion).
Banding
Unwanted pattern caused by a resolution mismatch of the image, output device, or lenticular lens.
Depth
Lenticular image effect that creates a three-dimensional illusion using multiple images (same as 3D).
Flip
Lenticular image effect when switching from one image to another.
Frame
One of the multiple image files interlaced to create a lenticular image.
Gauge
The thickness of a lenticular lens (same as thickness).
Ghosting
Unwanted visual artifact that does not completely turn off during an image transition.
Interlacing
The process of interweaving multiple frame (image) files into a single lenticular image.
Lens Count
The number of lenticules (ribs) counted per inch of a lenticular lens (same as LPI).
Lenticule
Single magnifying rib of a lenticular lens.
Lenticular Lens
Extruded clear plastic comprised of lenticules (ribs).
LPI
The number of lenticules (ribs) counted per inch of a lenticular lens (same as lens count).
Morph
Lenticular image effect that smoothly transitions from one image to another.
Motion
Lenticular image effect using multiple images to create the illusion of motion (same as animation).
Orientation
The reference to lens direction. Vertical lens orientation provides a side-to-side or walk-by motion. Horizontal lens orientation provided top-to-bottom motion and will provide the best motion and flip result. Note: A three-dimension effect requires a vertical lens.
Parrallax
The offsetting of visual planes to create the illusion of three-dimension.
Refresh
The jump a lenticular image makes while transitioning to the beginning frame image.
Thickness
The thickness of a lenticular lens (same as gauge).
View Distance
The distance the lenticular image will be viewed at. Hand-held and poster are the most common references.
Zoom
Lenticular image effect when enlarging a portion of an image.
Lenticular image effect that creates a three-dimensional illusion using multiple images (same as depth).
Alignment
The parallel positioning of a lenticular image to the lenticules (ribs) of the lens.
