ABSTRACT:
A method for forming an image useful as a lithographic printing plate is disclosed. The imageable precursor comprises a water solubilized phenolic resin made up of an insoluble phenolic resin and a surfactant. The precursor can be imaged with an imaging solution, either off press or on press, using ink jet imaging techniques. The resulting imaged precursor can be developed using an aqueous liquid, such as water or a fountain solution, either off press or on press.
