Abstract: An image-bearing element comprising of a white, translucent, metallized film article wherein the film article comprises a flexible, heat resistant, polymeric film material with opposite sides. The film material has deposited on a first side a metal coating which both reflects and transmits visible light and capable of transmitting from about 1% to about 70% of incident visible light cast thereon. The second side of the film material has a white outermost surface and has a visible light opacity of from about 0.5 to about 0.98.

Abstract: A white, partially translucent, metallized film article which having a flexible, heat resistant, polymeric film material with opposite sides. The film material has deposited on a first side a metal coating which is spectrally reflective and partially light transmissive in the visible region of the spectrum, is capable of transmitting from about 1% to about 70% of incident visible light cast thereon; the second side having a white outermost surface, and has a visible light opacity of from about 0.5 to about 0.98.

Abstract: A method of controlling developer activity in the processing of photosensitized printing plates; comprising, exposing a photographic test film, comprising, a film adapted to pass substantial amounts of light through some portions thereof and substantially lesser amounts of light through other portions thereof, preferably transparent portions and opaque portions, and having a background area and a plurality of insets separated from one another and surrounded by and separated by the background area, the background area having a plurality of regularly spaced dots, having a relatively small total dot perimeter per unit area and a constant dot size and adapted to pass substantial amounts of light through said dots, separated by lines adapted to transmit substantially lesser amounts of light through said lines, each of the insets having a plurality of regularly spaced dots, having a larger total dot perimeter than the small dot perimeter and constant dot size and adapted to pass small amounts of light through said
