ABSTRACT:
A lenticular array which is a body having a flat surface and an opposed surface with a plurality of convex lenses thereon is aligned with a substrate having a pattern therein by placing the lenticular array over the substrate with the flat surface facing the substrate. Radiant energy is directed through the substrate and the lenticular array to project the patterns onto the lens surface of the lenticular array. The lenticular array is moved with respect to the substrate until the images of the patterns are aligned on the surfaces of the lenses.
