Abstract (en)
[origin: EP0008760A2] The process for preparing offset printing blankets by applying a layer of porous, elastic material to a fibrous support layer is based on the finding that, if a layer of an expandable polyvinyl chloride plastisol, which will expand and gel when heated, is applied to the support layer the result is a printing cloth which produces noncrisp images in particular on the first copies. This disadvantage is remedied by a thin coating which, applied to the free surface of the porous layer, prevents the adverse effect of the plasticiser in the porous layer on image reproduction
