Abstract: A method of forming a partial retroreflector tool includes forming a substrate comprising a retroreflective microstructure pattern on a surface thereof. The surface of the substrate is machined to remove at least a portion of the retroreflective microstructure pattern to form a partial retroreflective microstructure pattern on the surface of the substrate to generate the partial retroreflector tool. A method of fabricating a partially retroreflective sheeting utilizing the partial retroreflector tool is also disclosed.
