Abstract

In a printing blanket comprising a reinforcement layer formed of more than one sheet of fabric, a compressive layer, and a surface rubber layer laid through a supporting body, the compressive layer is separated by a separation layer so as to be divided into two layers of a first compressive layer and a second compressive layer. Because the compressive layer is formed in a two-layer construction, normal printing pressure and abruptly applied excessive printing pressure can be efficiently absorbed. It is preferable that the first compressive layer close to the surface rubber layer has an air space amount of 0.10-0.20 mm, and the entire part of the first compressive layer and second compressive layer has an air space amount of 0.25 mm or more. It is also preferable that the hardness of the compressive layer is 50-90 JIS-A, and the separation layer has a hardness of 50 JIS-A-80 JID-D and a thickness of 0.05 mm.
