A method for preserving image squareness and image on image registration in a
system
having a plurality of imaging stations, each imaging station having an ROS. The
method includes adjusting the target skew of a reference ROS within one of the
plurality of imaging stations by the angular difference between the actual reference
ROS position and the target position for the reference ROS and adjusting the target
skew of the reference ROS by the skew of the reference ROS relative to the desired
skew for image squareness.
