A method and apparatus of applying a solution of a predetermined viscosity to photosensitive material to form a protective coating thereon

摘要

The present invention relates to a method and apparatus of applying a solution of a predetermined viscosity to photosensitive material to form a protective coating on the photosensitive material. The method and apparatus can be used in a photographic processing device, and the apparatus can be built into an existing or new photographic processor or added on as an accessory. The method and apparatus (1) is utilized to apply a viscous solution (3) to at least one surface of processed photosensitize materials (5) prior to drying in a manner that allows the solution to be uniformly applied to the at least one surface at a specific layer thickness. The viscous solution after drying functions as a protective coating which can protect the processed photosensitize material against scratches and moisture. The apparatus includes a control mechanism (19) which controls the thickness, uniformity and laydown amount of the applied viscous solution so as to insure that a uniform coating that provides protection to the entire surface of the processed photosensitize material is provided.
