ABSTRACT OF THE DISCLOSURE Method of fixing and adjusting a printing plate on a plate cylinder and device for carrying out the method.

The plate is stretched on the cylinder surface and its distal end is engaged between the jaws of a second clamping device located in the axial groove , and the jaws are tightened by means of screws . The plate is stretched by feeding hydraulic jacks set at spaced intervals along the lower jaw of the clamping device of which the pistons react against the adjacent radial face of the groove, thus moving the clamping device in the peripheral direction of the cylinder . After obtaining the desired adjustment the displaced clamping device is locked by tightening in a tightening body responsive to screws projections of the displaced clamping device in order to lock same, and the pressure in the hydraulic circuit is relieved. ---oooOooo---
