Abstract
A tubular printing blanket for a blanket cylinder in an offset printing press comprises a cylindrical sleeve, a compressible layer over the sleeve, and an inextensible layer over the compressible layer. The cylindrical sleeve is movable telescopically over a blanket cylinder. The compressible layer comprises a first seamless tubular body of elastomeric material containing compressible microspheres. The inextensible layer comprises a second seamless tubular body of elastomeric material containing a tubular sublayer of circumferentially inextensible material. A seamless tubular printing layer over the inextensible layer has a continuous, gapless cylindrical printing surface. Methods of manufacturing the tubular printing blanket are also disclosed.
