ABSTRACT:
A composition is provided which cleans, conditions, removes scratches, and finishes lithographic plates, the composition being an emulsion of an aqueous phase in an oil phase, the oil phase including a highly penetrating solvent such as mineral spirits, an oleophilic acid, and an emulsifying surfactant such as a non-ionic benzene sulfonate, while the aqueous phase includes a hydrophilic synthetic desensitizer such as a modified polyacrylamide, a gum desensitizer, a desensitizing agent such as phosphoric acid or derivatives thereof, a nitrate salt, and water. These compositions perform as plate cleaners, conditioners and scratch removers when put to use in the press room, and also are typically suitable for use as finishers for exposed and developed plates within the plate making room.
