Abstract
An ink jet image transfer lithographic apparatus is coupled to a source for supplying graphics and textual material to an ink jet printhead. The ink jet printhead melts a hydrophobic solid ink and sprays the ink onto a lithographic plate in a predetermined pattern. The solid ink solidifies upon contact with the plate. The plate is then mounted in a lithographic press for lithographic printing. As an alternative, the ink jet printhead may be mounted in a lithographic press for imaging a lithographic plate mounted in the lithographic press or for spraying ink directly onto the plate cylinder of the press. A succession of lithographic plates may be provided around the plate cylinder of the lithographic press and each plate discarded after use, leaving a clean plate on the plate cylinder.
