Abstract
A method generates and evaluates a fiducial pattern for an imaging system. The method includes generating a fiducial pattern for an image substrate, and measuring a difference between a structure of the fiducial pattern and at least one of a structure of a printing system and a structure of a measurement pattern to determine whether the structure of the fiducial pattern is distinguishable from at least one of the structure of the printing system and the structure of the measurement pattern.
