A lithographic plate is charged by a corona generating device. The image areas retain the charge with the non-image areas being grounded. The charged image is then developed electrostatically with a liquid ink to form a liquid image for proofing. This liquid image is transferred onto a copy sheet for review. The lithographic plate, which was used to make the proofing sheet, can then be mounted in an offset press and used in conventional lithography.
