Number 23 in 24 months United States Patent 5,819,661 Lewis, et. al. Oct. 13, 1998 ------------------------------------------------------------------------ Method and apparatus for laser imaging of lithographic printing members by thermal non-ablative transfer Abstract Apparatus and methods for rapid, efficient production of durable lithographic printing plates by a thermal-transfer process that does not involve ablation. In response to an imaging pulse, a transfer material reduces in viscosity to a flowable state. The material exhibits a higher melt adhesion for a plate substrate than for the carrier sheet to which it is initially bound, so that in a flowable state it transfers completely to the substrate. Following transfer, the carrier sheet, along with untransferred material, is removed from the substrate. ------------------------------------------------------------------------ Inventors: Lewis; Thomas E.
