PURPOSE:To obtain a registering device capable of accomplishing an automatic registering with an enhanced registering accuracy in the application to a flat-bed offset press. CONSTITUTION:In a flat-bed offset press provided with a printing platen 1 on which a glass substrate 15 serving as a printing body is placed and a movable frame 3 provided with a blanket cylinder rotating on the printing body, an optical sensor 4 is installed to the movable frame 3, and glass marks 5-1, 5-2 and platen marks 6-1, 6-2 are respectively provided on the glass substrate 15 and the printing platen 1. The glass marks 5-1, 5-2 and the platen marks 6-1, 6-2 are read by the optical sensor 4. Based on a relative misregistration amount between the both, the position of the glass substrate 15 is corrected. |
