Abstract
A compressible printing roller and method of making the same are provided wherein such roller comprises a central support, a tubular inner layer carried by the support and made of a microporous rubber material having cavities interconnected by passages, and a tubular outer layer disposed around the inner layer and made of a nonporous polymeric material with the layers cooperating to assure the roller provides optimum contact between the roller and material being coated thereby at comparatively small nip pressures.
