Summary:The invention relates to a method for changing printing plates on a cylinder, comprising the following rotating steps: a first rotation of the cylinder (3) in a first direction (7), in which a first printing plate (5) is detached from a circumferential surface (4) of the cylinder (3); a second rotation of the cylinder (3) in an opposite second direction (8), in which a second printing plate (6), which replaces the first printing plate (5), is mounted on the circumferential surface (4) of the cylinder (3); and comprising the following opening steps: opening the first clamping device (9) and releasing the front edge (5a) of the first printing plate (5); opening the second clamping device (10) and releasing the rear edge (5b) of the first printing plate (5); characterized in that both the first clamping device (9) and the second clamping device (10) are opened before the first rotation of the drum (3). The invention advantageously makes it possible to reduce the reloading time for changing printing plates. The i
