Printing plate and method of making using digital imaging photopolymerization

摘要

A printing plate is provided including a support assembly and a relief imaged surface formed directly on the surface of the support assembly by digital photopolymerization. The support assembly may be in the form of a cylindrical sleeve or a flat polymeric base. The printing plate is formed by providing a liquid photopolymer on the surface of the support assembly and irradiating the polymer with a source of actinic to form the relief image. The printing plate is reimagable and may be used in flexographic printing processes as well as other printing applications.
