Abstract (en)

[origin: WO0068353A1] A solvent system for removing ink and imaged coating from printing plates comprising a glycol ether ester and water, with or without ammonia or aminoethanol, and with or without a solubility enhancer. A solvent system for removing ink and imaged coating from printing plates comprising a glycol ether ester and aminoethanol. A solvent system for removing ink and imaged coating from printing plates comprising a glycol ether, water and ammonia or aminoethanol, with or without a solubility enhancer. A method of simultaneously removing adsorbed ink and imaged polymer coating from printing plates using these solvent systems. A method of cleaning used printing plates in-situ using these solvent systems.
