摘要

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 fo r removing ink and imaged coating from printing plates comprising a glycol eth er 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 printin g plates using these solvent systems. A method of cleaning used printing plate s in-situ using these solvent systems.
