Cube corner geometric structures in a substrate formed by both replicating and machining processes

Year	Description
2001	Invention patented by Kenneth L. Smith and Gerald M. Benson on June 14th, 2001. Abstract: A cube corner article having a structured surface of geometric structures, each geometric structure having a plurality of faces at least some of which are arranged as a cube corner element, is made by providing a first substrate having a plurality of grooves therein, replicating the first substrate in a second substrate, and forming a second plurality of grooves in the second substrate. Geometric structures in the second substrate are formed in part by replication of the first plurality of grooves and in part by the formation of the second plurality of grooves.
