Abstract
A method is furnished for producing a compressible layer for a printing blanket by heating a sheet-shaped intermediate layer of a rubber composition having a structure in which hollow microspheres are dispersed in matrix rubber for one to fifty minutes under certain defined conditions of vulcanizing pressure and temperature using a vulcanizer for applying heat and pressure in direct contact with the intermediate layer. The produced compressible layer exhibits superior compressibility and durability, is uniform in thickness and internal structure, and does not reduce the productivity of the printing blanket and increase the fabrication cost of the printing blanket.
