1. A printing drum mounting system comprising:
a rotatable shaft;
a first mount and a second mount arrangeable on the shaft to clamp a printing drum therebetween, wherein the first mount comprises a first engaging surface to form a mating contact with a corresponding first end surface of the printing drum and the second mount comprises a second engaging surface to form a mating contact with a corresponding second end surface of the printing drum;
a double-walled flexure to flexibly engage the first engaging surface and the shaft, the flexure to provide the first engaging surface with a single degree of freedom of axial movement relative to the shaft and to maintain mating contact between the first engaging surface and the first end surface of the printing drum as the printing drum thermally expands and contracts; and
a releasable fixing to align and rigidly engage the second engaging surface relative to the shaft.
