Beschreibung
Zusammenfassung:	A method for fabrication of a rear projection article forms an arrangement of refractive elements on one surface of a transparent support and forms an apertured surface on the opposite surface of the support. A photographic positive reversal emulsion is applied to the opposite surface of the substrate to form a light-sensitive layer. Visible light is directed, as exposure radiation, through the refractive elements, exposing the light sensitive layer to form an exposed layer. The exposed layer is developed photographically using a positive reversal process to form the apertured surface thereby.
