Abstract
Magnetic cylinders with an image plate or an offset blanket carrier plate have annular pole pieces and magnets which maximize either the resistance of the plate to peel-off or the attractive force intensity with a nominal displacement of the plate from the cylinder for typical operating conditions. The plates are precurved, preferably with a radius slightly less than the cylinder radius.
