<p>An electrophotographic printing machine in which a transparency light image is projected through a screen having a plurality of opaque regions. At least a portion of the opaque regions have a light reflecting surface on one side thereof and a light absorbing surface on the other side thereof. The screen is positioned so that the light reflecting surfaces of the opaque regions form a visual image of the transparency light image being projected therethrough. Incident light rays are absorbed by the absorbing surfaces of the opaque regions. The foregoing abstract is neither intended to define the invention disclosed in the specification, nor is it intended to be limiting as to the scope of the invention in any way.</p> |
