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 is utilized to apply a viscous solution to at least one surface of processed photosensitize materials 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 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.
