Patent ID: 6874420

Claim:
A registration optimization and/or correction system comprising: (1) means for obtaining an RGB image of gear-side and operator side marks on a web; (2) means for determining the [X,Y] coordinates of gear-side and operator side marks; (3) means for determining the [X,Y] center of said gear-side and/or said operator-side marks; (4) means for calculating absolute [X,Y] distance measurements from said RGB image and a traverse encoder; (5) means for calculating absolute [X,Y] coordinates for gear-side and operator-side duplicate and test station marks; (6) means for determining skew error; (7) means for determining fan-out error; (8) means for determining initial pre-registration error; (9) means for determining combined pre-registration error; (10) means for adjusting web print controls; wherein said means for adjusting web print controls is adjusted based on said skew error, said fan-out error, said initial pre-registration error, and/or said combined pre-registration error.
