ABSTRACT:
The present invention is directed to an apparatus and an associated method for achieving alignment between an image on a film and a lenticular material that is to be bonded to the film to permit the image to be viewed in 3D. The apparatus imparts a controlled bending of the lenticular material over the film such that the slight differences in length between the lenticular material and the film, caused by the bending, adjusts for changes in the line spacing of the lenticular material and or in the spacing of the image segments. Other embodiments of the invention provide for a controlled stretching of the film along its length and from side-to-side to again compensate for variations in the line spacing of the lenticular material or spacing of the image segments.
