Abstract: A printing system includes a media input location for storing a recording medium prior to transport within the printing system for subsequent printing; a light source directed toward an extended region of the media input location; an array of photosensors restricted to only a substantially perpendicular movement relative to a plane of the media input location; and an optical path including a first optical path section from the light source to the extended region of the media input location and a second optical path section from the extended region of the media input location to the array of photosensors.

Abstract: A black-and-white photographic developing composition has improved stability and is more compatible with the environment when discarded. The composition includes one or more ascorbic acid developing agents and a preservative (such as a sulfite) and is essentially free of hydroquinone and similar developing agents. Improved stability is provided using a sulfo-substituted organic compound as a stabilizing agent. Such compounds are either aliphatic sulfo compounds or hydroxy-free aromatic sulfo compounds.

Abstract: A two-part sepia toning kit can be used to provide desired stable, warm sepia toned images in black-and-white photographic positive or negative materials such as black-and-white photographic prints. One part of the kit includes a silver bleaching composition comprising a hexacyanoferrate as the bleaching agent and halide ions in a molar ratio of at least 2.25:1. The second part is a toning composition that includes a sulfur-containing toning agent.

Abstract: Color reversal photographic films are processed using a reversal solution comprising stannous ion and a quaternary ammonium compound as the sole microbial control agent, to reduce formation of visible biogrowth. The quaternary ammonium compound is present at very low concentrations of 1 to 20 ppm, and is preferably myristyltrimethyl ammonium bromide because it avoids precipitates with components that may leach out of some processed films.

Abstract: Color photographic films are processed using a final dye image stabilizing solution containing certain aromatic or heterocyclic aldehydes, acetals or hemiacetals, and a mixture of specific surfactants. One surfactant is a nonionic polyethoxylated, nonfluorinated compound, or an anionic non-fluorinated sulfate or sulfonate, and the second surfactant is a nonionic or anionic fluorinated compound. This processing solution provides processed films, with or without a magnetic backing layer, that are free of scum or other residues, non-tacky, and resistant to abrasion and fingerprinting. The stabilizing solution can be provided in concentrated form, particularly when a glycol is included.

Abstract: A photographic color developing composition includes a color developing agent and at least 0.005 g/l of an anti-tar agent. Such anti-tar agents include a fluoroalkylpolyethyleneoxy alcohol, polyvinyl alcohol, a polyethylene glycol, a free acid of an organic phosphate ester or a salt thereof, or a polyethyleneoxide(20) sorbitan monooleate Inclusion of these agents has been found to significant reduce or elimination tar formation during the processing of color photographic materials, especially color motion picture films.

Abstract: Color reversal photographic films are processed using a reversal solution comprising stannous ion and a quaternary ammonium compound as the sole biocide, to reduce formation of biogrowth. The quaternary ammonium compound is present at very low concentrations of 1 to 20 ppm, and is preferably myristyltrimethyl ammonium bromide because it avoids precipitates with components that leach out of processed films.

The color films can be more rapidly processed, for example, within 60 seconds for the stabilizing step.

Abstract: Color photographic materials are processed using a final rinse solution containing a water-soluble or water-dispersible glycol, and a mixture of specific surfactants. One surfactant is a nonionic polyethoxylated, nonfluorinated compound, or an anionic non-fluorinated sulfate or sulfonate, and the second surfactant is a nonionic or anionic fluorinated compound. This solution provides processed materials, with or without a magnetic backing layer, that are free of scum or other residues, non-tacky, and resistant to abrasion and fingerprinting.

Abstract: Silver halide photographic color films can be effectively stabilized using a chemical stabilizing kit of two concentrated chemical solutions that are mixed and diluted at least 5:1 when used. Each concentrated chemical solution contains some of the necessary chemicals for the processing solution, but keeping them individually packaged prior to use prevents biocide instability and other problems when all of the chemical components are mixed in concentrated form. One concentrated chemical solution includes hexamethylenetetramine and an alcoholamine such as diethanolamine. The other concentrated chemical solution includes the biocide(s) and one or more surfactants.

Abstract: A processing composition includes a combination of two different mercapto-substituted anti-sludging agents. The first compound is a conventional mercapto-substituted compound, and the second compound is a mercapto thiadiazole glycerol propoxylate having the formula I: ##STR1## This processing composition can be used to provide black-and-white development of both color reversal and black-and-white photographic elements, and particularly in high contrast graphic arts films.

Abstract: Various photographic films, that have already been photographically processed, can be cleaned or washed using an aqueous wash solution comprising a phospholipid in an amount of at least 50 ppm, to remove dust, dirt, or oily fingerprints. This solution can be particularly useful for rewashing color motion picture films.

Abstract: A stabilizing bath that provides image stability and uniform drainage of excess fluid to prevent drying spots and that reduces or eliminates the formation of residue on the base side of color negative films is comprised of hexamethylenetetramine, a nonionic polyethoxylated surfactant, and an anionic sulfate or sulfonate surfactant. The stabilizing bath is used as the final processing bath prior to drying. The nonionic surfactant provides uniform drainage of excess fluid and the anionic sulfate or sulfonate surfactant functions to reduce or eliminate the formation of residue on the base side of color negative films.

Abstract: A silver recovery element (10) for treating a photographic developer solution containing silver ions comprises a substrate (20) having thereon a hydrophilic colloid layer containing physical development nuclei. The invention also comprises a process for recovering silver from a photographic developer solution containing silver ions, such process comprising contacting the solution with the silver recovery element. The contacting is for a time sufficient to reduce the concentration of silver in the solution to a desired level. The recovery element and process for its use are useful in treating a seasoned photographic developer solution containing silver ions.
