ABSTRACT:
A system for prestripping alignment of color separations providing automatic registration of same on stripping, includes provision for using a set of carrier-related holes in a first color separation for establishing position of the first color separation on a hole-transfer table, and then for using fiducial indicia on the first color separation to establish position of a sensor system which in turn is used in conjunction with corresponding fiducial indicia on each of the remaining color separations to establish location for corresponding carrier-related holes which are then punched in each color separation using the hole transfer table.
