Method of extracting printing plate from plate cylinder involves ;locking element releasing printing plate, clamping bar, open duct, and deforming printing plate.

摘要

The back (9) and front (8) edges of the printing plate are tightly held by a locking element (5) in a gap in the plate cylinder (1). The back edge of a printing plate is released by the locking element of the plate cylinder; by the clamping bar (6) being displaced inside an open duct (4) in the plate cylinder. The printing plate (7) is plastically deformed at the back edge, near the clamping-bar. . The printing plate is removed from the plate cylinder.
