A method of calibrating a printing system for positioning at least one printed image, the printing system includes a first image bearing surface, the method includes: a) forming a background pattern and at least three fiducials on the first image bearing surface, wherein the background pattern is larger than a first printed image and the at least three fiducials are within an area formed by the first printed image; b) transferring a portion of the first printed image to a second image bearing surface; c) measuring a first residual image on the first image bearing surface, wherein the first residual image is a portion of the background pattern and the at least three fiducials remaining on the first image bearing surface after the step of transferring; and, d) calculating at least one calibration parameter for the printing system based on the measuring of the first residual image.
