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 on imaging and bending devices and a means for finely adjusting an initial position of the plate with respect to registration pins on the bender to bring the plate in registration with the specified 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 and the plate. The fine adjustment is accomplished by rotation of eccentric registration pins until the plate is within tolerance.
