Abstract
Apparatus (10) for registering printing plates (24) with a plurality of registration members (40A-40F), the apparatus (10) including a plate positioning system (64). The plate positioning system including a first member (50) adapted to pivot about a first pivot point and a plurality of second members (53A, 53B), each second member being pivotally coupled to the first member, and each second member comprising at least one element (58) adapted for engaging a printing plate. The apparatus includes a plurality of sensors (80A, 80B) adapted for detecting contact between the printing plates and the plurality of registration members. The plate positioning system includes a plurality of actuators (72A, 72B) coupled to the second members. An actuator in the plurality of actuators is selectively operated to apply force to an associated second member during a registration of a printing plate.
