Lithographic printing members include a traditional flood-exposed photopolymer layer applied to one or more layers based on certain metallic inorganic materials. The metallic inorganic material overlies a substrate, which is preferably a relatively thick metal for dimensional stability and strength, but may also be a polymeric or other material. An intermediate tying layer may anchor the metallic inorganic material to the substrate. The plate is exposed and developed in the conventional manner, with the portions of the metallic inorganic layer exposed by development serving as a hydrophilic printing surface (that is, a surface accepting fountain solution). |
