Abstract:
A printing blanket comprising:(1) a first compressive layer which is porous and seamless,(2) a non-expansion layer formed by spirally winding a thread in a circumferential direction of the blanket so that a distance between adjacent threads is not more than 0.5 mm,(3) a second compressive layer which is porous and seamless,(4) a surface printing layer which is seamless and non-compressive, anda cylindrical sleeve to be fit over a blanket cylinder,wherein said layers are laminated in this order with no other structural layers between said second compressive layer and said surface printing layer on an outer peripheral surface of said cylindrical sleeve directly or through a seamless adhesive layer, andthe thickness of the second compressive layer is from 0.05 to 0.45 mm, the thickness of the surface printing layer is from 0.05 to 0.45 mm, the total of the thickness of the surface printing layer and that of the second compressive layer is from 0.1 to 0.5 mm, and the thickness of the first compressive layer is from 0.1 to 2.0 mm.
