1. A printing blanket comprising:
- a base layer;
a compressible layer;
a first polymeric fabric reinforcing layer on said compressible layer;
wherein at least a portion of adjacent filaments of said fabric reinforcing layer have flowed together and bonded to form a reinforcing layer having reduced thickness; and
a printing surface layer on said fabric reinforcing layer.

Abstract
A printing blanket is provided which includes a reinforcing layer formed from a polymeric fabric reinforcing material which softens and flows at a temperature less than that used in the final curing step of forming the blanket or a polymeric reinforcing material having a thickness of between about 0.003 inches and 0.010 inches. The reinforcing layer provides a smooth surface to support an outer print surface layer and provides improved print performance while enabling a reduction in the overall thickness of the reinforcing layer.
