Abstract
Methods for making differentially pattern cured microstructured articles are disclosed, using a molding tool having a microstructured surface, a patterned irradiation to generate irradiate and non-irradiated regions in a radiation curable resin. Different combinations of molding tools and patterned irradiation provide numerous variants of differentially pattern cured microstructured articles without requiring costly modification of the molding tools.
