Abstract

A printing blanket which resists gauge loss throughout its useful life when subjected to printing nip pressures by retaining at least 95% of its original gauge throughout the useful life of the printing blanket. The printing blanket includes at least a printing surface layer and at least one reinforcing woven fabric ply and may also include a compressible layer. At least one, and preferably all, of the reinforcing woven fabric plies in the blanket construction are treated or fabricated to resist permanent deformation when subjected to printing nip pressures.
