Title: Innovations of William J Rozell in Lithographic Printing Technology
Introduction
William J Rozell, based in Vernon, CT, is a prominent inventor recognized for his extensive contributions to lithographic printing technology. With a remarkable portfolio of 42 patents, Rozell has made significant advancements that enhance the efficiency and quality of printing processes.
Latest Patents
Among his latest inventions are two noteworthy patents that address critical challenges in the development of lithographic printing plates. The first patent details a method of on-press plate development without contamination of fountain fluid. This innovative approach involves applying an emulsive film of press ink and fountain onto the entire photosensitive (PS) coating, allowing for the transfer of nonimage areas of the PS coating to a blanket roll while maintaining the integrity of the image areas on the substrate. This technique enables the particulate transfer of nonimage PS coating without dissolution or dispersion, ensuring a cleaner and more effective printing process.
The second patent is for a lithographic printing plate designed for in-solidus development on press. This invention features a substrate with a radiation-sensitive, negative-working PS resin coating that is non-ionically adhered. The PS coating, which is soluble in non-aqueous solvents, possesses the unique quality of being mechanically pulled off the substrate by press ink as particulates, without dissolving or dispersing into the ink. This advancement provides printers with enhanced control and efficiency during the printing process.
