Method of extending the useful life and enhancing performance of lithographic printing plates

摘要

A method of extending the useful life and/or enhancing the performance of wet or dry lithographic printing plates. A strong curable composition that adheres to the ink-receptive plate areas is first applied to an imaged plate. After removal of the composition from non-image plate areas, it is cured, thereby augmenting the resilience of the ink-receptive plate areas. If imaging of the plate results in surface recesses, the cured composition can enhance plate performance by making the entire surface coplanar.
