ABSTRACT:
A lithographic printing plate that is transformable by spark-discharge techniques so as to change its affinity for ink. The plate features a layered structure including an ink-receptive substrate, a conductive layer and an ink-repellent coating. The ink-repellent coating contains a dispersion of image-support pigments that promote straight-line travel of the spark to the surface of the plate, thereby promoting accurate imaging.
