Abstract
Lithographic printing members utilize, as an ink-accepting layer, a hard, inorganic, and generally covalent material that exhibits sufficient flexibility (at the deposition thicknesses envisioned) to accommodate flexing and bending. This layer may overlie a relatively heavy, metal plate substrate or support, resulting in a structure whose permanent layers all share the physical properties of inorganic materials. The printing member may also be provided with a protective layer that serves a variety of beneficial functions, including protection against handling and environmental damage and extension of plate shelf life, but which also is removed during the printing make-ready process.
