Abstract
An electrostatic charge is selectively applied to the anodized surface of an anodized aluminum plate in a predetermined pattern corresponding to the image to be printed, a liquid toner is applied to the charged portions of the anodized surface and the toner is fixed to the anodized surface to provide an imaged lithographic printing plate. The printing plate made by the method may be used to make lithographic prints by applying printing ink to the imaged portions of the plate and transferring the printing ink from the lithographic printing plate to a substrate.
