Abstract
A method of making an angular selective light control sheeting is disclosed. The method includes providing a sheet of an optically transmissive elastic material, providing a slitting blade, advancing the slitting blade into the optically transmissive elastic material to a predetermined depth, moving the slitting blade relatively to the sheet along a straight or curvilinear path so as to form a channel in the elastic material, and introducing an opaque material into the channel.
