ABSTRACT:
A photocomposer includes a fixed rearwardly inclined backboard for supporting a sensitized lithographic plate. To substantially reduce the weight of the backboard and its supporting structure, the main portion of the backboard is of cellular construction. Depressible register pins for positioning the lithographic plate are mounted on the backboard. Each pin is part of an assembly constructed to readily permit transverse adjustment of the pins.
