I work for the world leader in lenticular printing, Big3D.com. Give me a call at 559-233-3380. We do one-offs all the time. Most of the other answers to your question will steer you wrong. Photolabs typically do not offer lenticular, and access to lenticular lens material is difficult, making it hard to do your own. Lenticular 3d Software freeware for FREE downloads at WinSite. IMAgen is free 3D generating software. The only 3D software to directly integrate with Flash through the Swift 3D File Importer and SmartLayer Technology and exports to Microsoft XAML. Lentigram is a NEW software package for Windows 64bits, Mac and Linux including different command line tools: Pitchtest, a program to calculate the mechanical pitch of a lenticular sheet. Interlacer, a program to interlace a sequence of images mainly focused on the creation of orthoscopic 3D images.
Lenticular Printing Technology
We all must have seen animation in printed images such as winking of eyes, dancing image, changing graphics - commonly told by people as 3D effect but actually it is lenticular effect. This effect is nothing but in actual manner, it is a specialised image generated with the help of a specialised printing process known as Lenticular Printing and the substrate used in the process is Lenticular sheets or Lenticular Lens. Though mainly found in children toys, collection Lenticular lens is finding application in number of other areas as well. One of them is communication through Packaging and as a marketing tool to show products in motion. Let us have a look at the technology and where we can get this.
Lenticular Sheet/Lens
Lenticular lens are the piece of extruded plastic sheets having repeating rows of convex lenses (lenticules) on the front surface of the material, and a flat surface on the back side of the material that can either be printed on directly, or have a pre-printed graphic mounted to it (depending on the process of printing).
Lenticular Printing
Lenticular printing is a specialized printing process which utilizes a combination of specially prepared graphics that are designed to perfectly work together with lenticular lens to create printed images that have the illusion of depth or the ability to change or move as the image is viewed from different angles. The process of preparing graphics for use with a lenticular lens is commonly called “interlacing”. Interlacing is the process of creating a lenticular image from a set of 2D images. A small strip is taken from each 2D image and is combined in one image to match a specific lens pitch. An interlaced image is made up of repeating slices of multiple images that are either multiple views of one scene for 3D, or multiple frames of an animated or multi-image sequence. These divided strips of the images are interlaced together. The interlaced image is then printed in register (perfectly alignment) underneath to the lenticular lens in order for the effect to work.
Types of lenticular prints
There are three distinct types of lenticular prints, distinguished by how great a change in angle of view is required to change the image:
- Transforming prints: Here two or more very different pictures are used, and the lenses are designed to require a relatively large change in angle of view to switch from one image to another. This allows viewers to easily see the original images, since small movements cause no change. Larger movement of the viewer or the print causes the image to flip from one image to another. (The 'flip effect'.)
- Animated prints: Here the distance between different angles of view is 'medium', so that while both eyes usually see the same picture, moving a little bit switches to the next picture in the series. Usually many sequential images would be used, with only small differences between each image and the next. This can be used to create an image that moves ('motion effect'), or can create a 'zoom' or 'morph' effect, in which part of the image expands in size or changes shape as the angle of view changes.
.
- Stereoscopic effects: Here the change in viewing angle needed to change images is small, so that each eye sees a slightly different view. This creates a 3D effect without requiring special glasses. Lens Design Lenticular lens has various designs. Depending on the sort of animation and the printing process to be used to produce the lenticular prints, different lenticular lens designs exist. The thickness and viewing angle of the lenticules are different. It is also found that angle of lenticular also differ. A narrow angle will give an optimal 3D effect, and a wide angle will work best for an animation effect. The lenticules for animation effects may run vertically or horizontally. However, better results – meaning cleaner action and far less chances of ghosting – when the lenticules are in the horizontal direction. For larger, more stationary pieces such as a poster or P.O.P. display, the vertical direction should be used since it requires the viewer to move rather than the piece.
