ABSTRACT:
A method and apparatus for the registered application of printing plates to a printing cylinder applies the printing plates to the jacket face of the printing cylinder exactly registered and free of bubbles and warping. The printing plate is clamped in a frictionally connected manner in a stretched position by holding arms and is exactly registered in a horizontal and vertical set position. The plate is then aligned and spaced apart from the printing cylinder and is maintained in a frictionally connected manner. Subsequently, the printing plate is brought into line contact with the jacket and is then pressed against it. The printing plate is pressed down against the cylinder jacket, starting at the contact line, and the pressing force is then applied to the plate circumferentially around the cylinder from the initial contact line.
