3D depth 

Involving printing on to a transparent clear plastic with an array of optical lens ribs across the surface, lenticular printing is the only specialism in the world. Then on the back of the film images are printed, and they create the moving image when viewed through the optical lens on the front.

Furthermore, to this costly print complex software and pre-press digital artwork preparation has historically made access. 

3D Printing from Lenticular Printing Wholesale

Within the brain three-dimensional vision is achieved by merging the image data from the left and right eyes. Such a phenomenon is referred to as parallax. When viewed from slightly different positions it shows the apparent placement of an object relative to its background.

Moreover, a stereoscopic effect is created by the web-based conversion process by converting standard 2D imagery into a multi-layer 3D file. Each lenticule creates a stereo pair when printed onto the reverse side of a lenticular sheet, thus without the need to wear special glasses, it allows the viewer to have a 3D depth effect from various angles.

Flip Printing

Two images are contained in a lenticular effect in its simplest form and it shows to the viewer one at a time as his/her viewing angle to the lens sheets changes. Behind a lenticule, the software automatically interlaces 50% of each image. By the movement of the head to the left, one full image comes into view and then to the right.

However, there is the enormous creative potential of this product from lenticular printing manufacturer, offering you the opportunity to use extreme contrasts of the image to project your promotional message visually.

With personalized communication, we can also combine lenticular print so that your data can drive the message behind the image!
