ABSTRACT:
A method for improving die-cutting involving first creating a back plate footprint, possessing impressions of the imperfections found in the cutting surface of a die-cutting machine. This method provides die-cutters a simple, inexpensive way to dramatically improve the alignment of die-cutting knives for making cuts. The method uses a malleable material that will readily receive an impression of imperfections of a cutting surface when some pressure is provided, but the material must also be capable of hardening into a useable solid material. The principles of this method may be applied to all die-cutting machines by making a back plate footprint of the die-cutter in question and by properly inserting it back into the chase where the impressions contained therein will press down on the material below it so as to better align the cutting knives of the die being used.
