System for projecting in polychrome form original black films which is characterized by the same use in printing as in the projection of an auxiliary objective of mechanical adaptation to both machines which is constituted by a cylinder carrying a conventional focal lens in a external end and a prismatic and more concretely quadrangular pyramidal glass lens affected by the essential feature of being convex for printing and concave for the projection that is located at the opposite end of the lens; a plane translucent crystal disk interposed between both lenses in which the perceived image is formed.
