ABSTRACT:
The invention is directed to a method for producing a multi-layered elastic printing blanket such as an offset printing blanket having a structured surface. The printing blanket includes reinforcement carrier layers, an elastic intermediate layer and a cover layer made of rubber or a rubber-like material. The cover layer has a structured surface which is formed by first applying particles, which volatilize under the application of heat, to the unvulcanized cover layer and thereafter applying heat under the application of force thereby causing the particles to assume a gaseous state while generating pressures which impart a roughness to the surface of the cover layer.
