An offset blanket (50) having an improved adhesive structure (40) for releasible adherence to a blanket cylinder of an offset printing apparatus. The adhesive structure (40) includes a composite of a hot-melt adhesive film (44) bonded to a layer of pressure sensitive adhesive (42) disposed on a siliconized surface of a release layer (46). A method for forming an offset blanket is also disclosed in which a layer of a pressure sensitive adhesive is bonded to the cloth side of an offset blanket utilizing a hot-melt adhesive film. In the bonding step, a composite formed of the pressure sensitive layer bonded to a hot-melt adhesive film is nipped together with the offset blanket such that the cloth side of the blanket faces the hot-melt adhesive film. Sufficient heat and pressure are applied to activate the hot-melt adhesive film. |
