Abstract
Transportation of a lithographic plate uses an indexer to load plates into pods for delivery to a press cylinder via a pod elevator or a pod cart. The plates are imprinted with a bar code, imaged, punched, bent, sheared, corner notched, and registered to a press cylinder. The plates are loaded into the indexer, which moves the loaded plates into a position in alignment with designated pod compartments, and loads the plates into each of the designated pod compartments by indexed movement of an elevator within the indexer. The pod elevator or the pod cart moves the pods proximate to a press cylinder where the plates are unloaded from the pod and loaded onto a press cylinder. A computing device, such as a PLC, directs the process. A vision system senses information from the indexer, pod, pod elevator, and the plate for feedback to a PLC, which initiates operations of foregoing.

Abstract
The method and apparatus for registration of a lithographic plate includes a means for ensuring that the plate is in contact with registration pins (401A, 401B, 401C) on imaging and bending devices (18, 19) and a means (422) for finely adjusting an initial position of the plate with respect to registration pins (401A, 401B, 401C) on the bender to bring the plate in registration with the specificed plate lock-up position on the press cylinder. Three separate electrical circuits ensure that the plate is in contact with the registration pins if each separate circuit is able to conduct current between the respective pins (401A, 401B, 401C) and the plate. The fine adjustment is accomplished by rotation of eccentric registration pins (401A, 401B, 401C) until the plate is within tolerance.
