Process for the production of a printing comprimivel coverage, and coverage of impression produced by this process comprimivel

摘要

A laminated printing blanket having compressible and resilient properties and a method for its production are provided. The compressible characteristics are provided by disposing a compressible intermediate layer having voids, between a base ply and a surface layer. The voids in the intermediate layer are produced by dispersing a blowing agent in an elastomer, sandwiching the elastomer containing the blowing agent between two fabric layers, and activating the blowing agent to produce voids. By activating the blowing agent before disposing the intermediate layer between the base ply and the surface layer, the gases from the blowing agent are prevented from migrating to the base ply or to the surface layer.
