Title: Ernest W. Ellis: A Pioneer in Lithographic Innovations
Introduction
Ernest W. Ellis, based in Harvard, MA, is a notable inventor with an impressive portfolio of 45 patents. His work primarily focuses on innovations in lithographic imaging, which have significantly advanced the capabilities and efficiency of printing technologies.
Latest Patents
Among his latest contributions to the field are two significant patents. The first, "Wet lithographic imaging with metal-based printing members," describes a process where lithographic printing utilizes printing members featuring a hydrophilic-surfaced metal support. A polymeric layer covers this support, which is designed to absorb imaging radiation and remain soluble in an ink-repellent liquid, such as fountain solution. This dual-layer system allows for an effective ink-carrying oleophilic layer during the printing process, enhancing print quality and durability.
The second patent, "Lithographic imaging with constructions having inorganic oleophilic layers," presents innovative plate constructions that utilize a durable hydrophilic layer and a hard, inorganic, oleophilic layer. This design enhances the efficiency of thermal insulation, preventing heat dissipation into the substrate, thus facilitating optimum ablation. Notably, this method allows corrections post-imaging, leveraging traditional means without compromising on quality.
Career Highlights
During his career, Ellis has worked with prominent companies, including Polaroid Corporation and Presstek, Inc. His expertise in lithography and printing technology has established him as a key figure in advancing these fields, contributing to their evolution with his inventive solutions.
