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.

Abstract: Molds and methods for forming molds used to make retroreflective articles are disclosed. The mold includes a plurality of shims joined together wherein each of the shims comprises a plurality of alternating cube corners. Each of the cube corners includes three facets each comprising a planar surface, four exterior sides, and three interior edges. The three interior edges meet at an apex, wherein each of the cube corners shares, with an adjacent one of the cube corners, at least one exterior side intersected by a respective one of the interior edges of each of the adjacent cube corners. A retroreflective article is formed using the mold and the retroreflective article includes goemetric structures corresponding to the cube corners of the plurality of shims of the mold.
