The present application is directed methods of manufacturing dual image substrates. In one embodiment, a light transmitting film is coated with a light shielding substance to provide light shielding areas and a major surface of the film is structured. In another embodiment, a light shielding film is structured to provide light transmitting areas. In another embodiment, a film is printed and then structured to provide light transmitting areas. In another embodiment, a light transmitting film is structured, and then coated with a light shielding coating. The coating is then removed from portions of the structured surface to provide light transmitting areas. The film may also be structured by casting on a structured liner.
