Abstract
Methods of identifying and measuring resolution error in a print device are disclosed. The methods include processing a scan of a document on which targets are printed at known reference locations. The system identifies and performs a 1D Hough transform process on each of the targets. In the process, the system measures differences between an identified location for each target and an expected location for each target. The system then uses the difference to measure the document's image resolution and estimate resolution error, if any, in the document.
