An offset printing press is provided. The offset printing press includes an image cylinder, a blanket cylinder having an axially convex outer surface, and a printing blanket disposed over the axially convex outer surface, the printing blanket including a carrier sleeve layer having at least one axially convex surface. An axially profiled shim is also provided.

Printing blanket with convex carrier layer

A printing blanket includes a carrier sleeve layer having at least one axially convex surface and a print layer disposed over the carrier sleeve layer. A blanket cylinder with a convex outer surface and a convex shim is also provided. An offset printing press is also provided.

A tubular printing blanket having an axial center has a carrier sleeve layer having a uniform thickness, a compressible layer, a reinforcing layer over the compressible layer, and a print layer disposed over the reinforcing layer. At least one of the reinforcing layer and the compressible layers has a non-uniform thickness so as to be thicker in the axial center. An outer surface of the print layer is convex.

Printing blanket with convex outer print surface

A printing unit including a rigid cylinder rotatable about an axis of rotation, a plurality of inflatable bladders disposed on a circumferential surface of the cylinder, and a first fluid supply regulation unit configured to supply a first fluid to a first set of inflatable bladders of the plurality of inflatable bladders and to regulate a first fluid pressure inside the first set inflatable bladders. In addition, a method for mounting a sleeve-shaped printing sock onto a blanket cylinder of an offset printing press, in which a set of inflatable bladders disposed at an outer region of the blanket cylinder are at least partially deflated. The sleeve-shaped printing sock is slid over one end of the blanket cylinder so that the printing sock at least partially surrounds a circumference of the blanket cylinder. The set of inflatable bladders are then inflated so that the printing sock fits tightly around the circumference of the blanket cylinder.

Blanket cylinder with integrated compressible layer

A tubular printing blanket including a tubular print layer, a tubular isotropic plastic reinforcing layer underneath the print layer, a compressible layer underneath the reinforcing layer, and a sleeve for supporting, directly or indirectly, the compressible layer. es axial stability due to its isotropic nature and the plastic material. Also disclosed is a method for manufacturing a tubular printing blanket including forming a tubular reinforcing layer and sliding the tubular reinforcing layer over a compressible layer. Furthermore, a device for manufacturing a tubular printing blanket is also provided. A first build cylinder has an outer diameter. A mandrel cap can be attached to one end of the build cylinder, the mandrel cap having an outer diameter larger than the build cylinder outer diameter.
