Abstract
The offset blanket of the present invention has a structure comprising no reinforcing layer between its compressive layer and its surface printing layer. The surface printing layer has a thickness in the range of 5 to 20% based on the thickness of the whole blanket, and a hardness of the rubber which constitutes the surface printing layer which is in the range of 40.degree. to 70.degree. Type A, JIS K 6301. The compressive layer has a foam content (void volume) in the range of 30 to 60% and a thickness in the range of 10 to 30% based on the thickness of the whole blanket and a hardness of the rubber matrix constituting the compressive layer which is in the range of 40.degree. to 80.degree. Type A, JIS K 6301. Therefore, the offset blanket of the present invention is superior in paper feeding properties. Further, misregistry can be inhibited and solid inking properties are not deteriorated.
