How do lenticular images work

Multiple images can also be layered together to create the same effect, and if enough images are interlaced, it can result in quite lifelike animations. In addition, by layering progressively larger images together, a lenticular image can be created that gives the effect of zooming in or out.

Instead of layering different images together, a single image is separated into multiple layers. By interlacing these different layers together, the technique can be used to create the appearance of depth between the various elements in the image. When creating animated lenticular images, the original digital images can be split either vertically or horizontally with the lens then matching that direction. This choice affects whether the animation will occur when the viewing angle changes from left to right or up and down.

Most people choose to split the images horizontally so that the animation will occur as the card is tilted up and down and this choice tends to work better. Stereoscopic 3D lenticular images are always split vertically and thus feature vertical lenticular lens.

However, it does take skill and knowledge to know how to properly interlace the images so that they match the corresponding lenses and getting great results takes a lot of experience. English en.

What is lenticular printing. A printing technology that uses a lenticular plastic to produce astonishing images with the illusion of motion and 3D. What lenticular effects can be achieved. Flip and animation The lenticular flip effect combines two or more very different images that change from one to the other as the angle of observation of the print changes.

How lenticular works Lenticular printing combines two main elements: a special plastic sheet and an interlaced image that is processed in a specific way. Step 3 The lens isolates and amplifies the interlaced image underneath it in such a way that only one original image at a time can be seen. How 3D lenticular works If the lens array is placed vertically, each eye sees a different image and creates the illusion of a 3D image. As the print moves, the diffraction of the lenses directs different image stripes towards your eyes, and the image appears to change.

Depth for the 3D illusion is achieved by parallax: each of your eyes sees a different light path through the lenses, one set for the left half and the other set for the right, which your brain interprets the result as stereoscopic depth. As a general rule, for motion the lenses will be arranged vertically for poster-type images that people move past, or horizontally for r.

With stereo 3D the lenses always run vertically. The lpi lens from Lenstar is only microns thick, but requires a high res printing process for smooth effects. Low lens pitches such as 20 to 40 lpi mean that the plastic has to be thicker and in turn it costs more. DP Lenticular, which distributes Lenstar in EMEA, commissioned the development of a 28 lpi lens material that managing director Daniel Pierret is particularly proud of.

As an intermediate between the established 20 and 40 lpi materials, 28 lpi is thinner and so cheaper then 20 lpi, but thick enough to allow wide angle viewing, plenty of frames and smoother transitions or more 3D parallax than 40 lpi. The higher the pitch ie narrower the fewer stripes sets you can fit in. As you'd want some detail in each stripe, you need a high true resolution to achieve that from an inkjet.

Large format but short run lenticular work was commonly done on digital film recorders such as the Durst Lambda. However these are out of production and getting rarer out in the real world. As UV inkjets have increased in resolution and quality, they have become more and more suitable for direct printing onto the back of lenticular lens material. Again, alignment is critical. The resolution is increasing, yes. Not just the physical resolution but the interpolations, so there is difference between the print and the head directions.

Rather than turning an image on or off like the flip effect, the morph element transforms one visual element into another. The morph animation effect is a great way to show a retroactive comparison, such as a previous logo or product to a new one. While these elements can be used individually, many times you will see combinations of the effects within the same product.

Combining lenticular effects can create brilliant results. However, careful preparation and planning must be executed in order to create a successful result. Then, storyboard your concept. Creating a storyboard will help convey how the lenticular layers will play off of each other. When looking for lenticular printing services, a great way to know if you are choosing an adequate lenticular printing company is looking at their past work.

Although there are many factors to consider, lenticular printing companies that execute the following are likely to create a stunning design for you.
