ABSTRACT:
A method as disclosed for preventing the formation of Newton ring light patterns between a transparency or photographic negative and a transparent mounting surface such as a sheet of glass. The method comprises the application of a thin film of a substantially transparent resin to form a matte surface finish on the surface of the transparency to be applied against the mounting surface and then mounting the transparency or equivalent to the mounting surface with the resin film interposed therebetween, such that the matte resin film serves as a spacer and also reduces reflection of light between the transparency surface and the mounting surface.
