Abstract
An optical film having a first surface, an opposing second surface, and a thickness normal to the first and second surfaces is cut. Cutting the film forms a channel at least partially through the thickness of the film. A light control material is printed proximate to a surface of the film. The ink traverses through the channel by capillary motion.
