    摘要: A method of forming a cylindrical printing article having a unitary compressible laminate and which includes a rotatable support in the form of a cylinder. This method comprises forming a compressible laminate having upper and lower surfaces and a substantially uniform thickness from at least a printing face which forms the upper surface and a compressible layer positioned beneath the printing face. The compressible layer contains a plurality of compressible cells dispersed therein and has first and second surfaces, with the first surface bonded to an adjacent surface of the printing face. In another step, the first surface of the compressible layer is formed with a profile having a raised central portion so that the compressible layer is spaced closer to the upper surface of the printing face in the center of the laminate than at the ends. Preferably, this laminate is cylindrical and is in the form of a printing blanket or printing roller.
