Claim:
An apparatus comprising: (a) a web drive mechanism engaging a support web to movably guide said support web wherein said support web is coated with a layer of a radiation curable material; (b) a photomask loop which comprises a pattern corresponding in form to said well-defined structures for selective imagewise exposure of said radiation curable material; (c) a photomask alignment mechanism capable of aligning at least a portion of said photomask loop in generally parallel orientation to at least a portion of said support web; (d) a photomask drive mechanism to move at least a portion of said photomask loop and at least a portion of said support web in parallel in substantially the same direction; (e) a radiation source mounted in cooperative alignment with said photomask loop and said support web to allow passage of radiation through a portion of said photomask loop directly onto said radiation curable material coated on a portion of said support web, which is in generally parallel orientation with said portion of said photomask loop through which the radiation passes, for selective imagewise exposure of said radiation curable material; and (f) a solvent application mechanism for the application of at least a solvent for removing unexposed portion of said radiation curable material.
