Claim 9:
10. The digital printing system of claim 1, wherein the in track position correction function is determined using a processing including:
i) providing digital image data for a test target including a plurality of alignment marks positioned at predefined cross-track positions;
ii) printing the test target using the digital printing system to provide a printed test target;
iii) using a digital image capture system to capture an image of the printed test target;
iv) using a data processing system to automatically analyze the captured image to determine a measured in-track position for each of the alignment marks;
v) comparing the measured in-track positions for the alignment marks to reference in-track positions to determine measured in-track position errors; and
vi) determining the non-linear in-track position correction function specifying in-track position corrections to be applied as a function of cross-track position responsive to the measured in-track position errors, wherein the in-track position corrections are quantized to integer in-track position corrections.
