ABSTRACT:
A printing blanket especially suited for use in offset lithography is provided by permanently laminating together an oil-resistant continuous rubber ink transfer layer, a strong thin tough synthetic foundation sheet, and a layer of incompressible elastomer having dispersed and bonded therein numerous minute frangible rigid-walled bubbles that have been broken uniformly throughout the elastomer layer to make it compressible.
