How it works
Lenticular print could be described as a specially prepared image which allows viewing different images at different angles when connected with the lenticular lens. Interlaced graphics is a combination of two or more images. Lenticular material is a sheet of plastic with extruded lenticulas (lens). These lens have to be perfectly aligned to the graphics.
Depending on viewing angle each lenicula works as magnifying glass. It zooms a piece of graphics which is underneath. The whole cluster of such lens gives a view of the whole picture. Changing the angle of viewing causes changing of images under the lens. It gives a sensation of motion or depth. If lens are parallel to both eyes – we will see the same image at a time.
If lens are perpendicular to your eyes – each eye will see different image – in this case 3D sensation is possible.
