| titleOfInvention | Treating a developed gelatin silver halide emulsion layer element with acetic acid and dischromate ions |
| abstract | This invention relates to the production of a positive-printing lithographic printing plate. The process utilizes an improved stop-bath solution which may be used with a wide variety of emulsions and developer solutions. One of the outstanding features of the invention is that exposure of the plate element to a positive original results in development of the plate element as a photographic negative image which will enable a press to print a positive copy. This is accomplished by treating the photographically developed plate in a stop-bath containing an oxidizing agent, such as potassium dichromate, which is capable of reacting with unoxidized developing agent, such as hydroquinone, in the non-image areas of the plate to make these areas oleophilic through a mechanism akin to polymerization or tanning. |
