Abstract:
1. A printing blanket, comprising a reinforcement layer formed of at least one sheet of fabric, a compressive layer, and a surface rubber layer laid on said compressive layer through a supporting body which is laid on said compressive layer, wherein said compressive layer is separated by a separation layer, which is formed by one or more layers of elastomer, so as to be divided into two layers of a first compressive layer and second compressive layer, so as to absorb normal printing pressure at the first compressive layer and to absorb rapidly applied over-printing pressure at the second compressive layer, an air space amount of said first compressive layer is 0.10-0.20 mm while a total air space amount of the first and second compressive layers is 0.25 mm or more, and a hardness of said separation layer is 70 JIS-A-80 JIS-D and a thickness of said separation layer is 0.05 mm or more.
