Abstract
A multi-layer, positive-working lithographic printing plate precursor can be imaged with infrared radiation and processed in a single step using a single processing solution that has a pH greater than 6 and up to about 11. This single processing solution both develops the imaged precursor and provides a protective coating that need not be rinsed off before lithographic printing.
