Abstract (en)
This invention relates to a sheet-fed offset printing press including a gear (3) driven by an upstream drive motor (1A), a gear (2) rotationally driven by the upstream drive motor (1A) through the gear (3), an impression cylinder (23) of an upstream printing unit group (20A), and a transfer cylinder (24) of a downstream printing unit group (20B). The impression cylinder (23) is rotationally driven by the gear (2) and has a holding portion for holding a paper sheet W, The transfer cylinder (24) is rotationally driven by a downstream drive motor (1B) and has a holding portion for receiving the paper sheet W from the holding portion of the impression cylinder (23). The printing press further includes an impression-cylinder-side peripheral speed measuring device (6A) for measuring the peripheral speed of the impression cylinder (23) and a transfer-cylinder-side peripheral speed measuring device (6B) for measuring the peripheral speed of the transfer cylinder (24). The rotational phase difference between the impression and transfer cylinders (23, 24) is obtained from signals from the impression-cylinder-side and transfer-cylinder-side peripheral speed measuring devices (6A, 6B).
