ABSTRACT:
Preprinted duplicating masters for producing printed copies, with or without spirit duplicating fluids, comprising a foundation sheet reverse printed in a predetermined pattern with an imaging material which produces copies upon the application of pressure alone, although the spirit duplicating process can be used. The imaging material is applied as a synthetic polymeric resin disperion having an ink composition therein and is subsequently heated to gel but not fuse the resin so that the ink composition will be retained therein but will be releasable and transferable in a predetermined pattern to a substrate by at least the application of pressure alone. A protective cover sheet is placed over the printing to prevent inadvertent and accidental transfer of the ink composition.
