Abstract:
A process for curing a photosensitive resin, which process comprises the steps of:(a) providing a liquid photosensitive resin disposed on a working surface, wherein the working surface is having machine direction and having has a cross-machine direction perpendicular to said machine direction;(b) providing a source of curing radiation capable of curing said photosensitive resin;(c) providing a plurality of collimating elements;(d) disposing said collimating elements intermediate said photosensitive resin and said source of curing radiation such that said collimating elements are substantially perpendicular to a general plane of said liquid photosensitive resin and are spaced from one another at a distance in the cross-machine direction, wherein at least one pair of the mutually adjacent collimating elements form a machine-directional clearance and a cross-machine directional clearance therebetween, said machine-directional clearance being greater than said cross-machine-directional clearance;(e) moving said photosensitive resin relative to said plurality of collimating elements in said machine direction; and(f) curing said photosensitive resin with said curing radiation from said source of curing radiation.
