ABSTRACT:
Duplicating equipment is provided for printing on both faces of the same sheet or, in the alternative, making two impressions on the same face (e.g., in different colors) by means of two printing heads. Both printing heads are served with masters from a single supply point, the masters being fed in proper order and attached to the master cylinder of the appropriate printing head automatically. In one form of the invention, the single master supply point takes the form of a single master maker and converter.
