Abstract
Electrode-driver circuits for use with non-contact spark-discharge imaging systems. The circuits rapidly produce short-duration, high-voltage pulses that cause the discharge of a spark to the surface of a printing plate; they feature short rise times, rapid operation and clean decays, thereby facilitating high-speed spark-discharge imaging.
