Abstract
A lithographic printing plate that is transformable by spark-discharge techniques so as to change its affinity for ink. The plate features a metal substrate and includes a conductive layer and an ink-adhesive coating. The plate can also include a heat-resistant insulating layer, or can be laminated using an adhesive that serves this function.
