Patent ID: 7182007

Claim:
A method of cutting and/or scoring a substrate according to an amendable cutting plan relative to graphics printed on an upper or lower surface of the substrate, the method comprising the following steps: (a) pre-printing on said surface of said substrate said graphics, and at least a first registration mark and a second registration mark; (b) automatically transporting said substrate from an in-stack region to a cutting table station along an x-axis, said cutting table station defining a reference frame; (c) while step (b) is carried out, optically detecting presence of said first registration mark and detecting position thereof relative to said cutting table station reference frame; (d) while step (b) is carried out and subsequent to step (c), detecting presence of said second registration mark and detecting position thereof relative to said cutting table station reference frame; (e) using positional information acquired at step (c) and at step (d) to amend said cutting plan as needed to account for actual position and orientation of said substrate on said cutting table station; and (f) cutting and/or scoring said substrate according to said cutting plan as amended at step (e).
