ABSTRACT:
To provide a development system for lithographic printing plate precursors using a neutral developer, capable of preventing the non-image area of the resulting printing plates from being stained. In developing a lithographic printing plate precursor with a neutral developer having a pH of from 5.8 to 8.6, ultrasonic waves and/or an electric current are imparted to the neutral developer.
