Abstract:
A method for aligning an image capture device for a print device includes providing a capture stage on which an object to be imaged by the capture device is placed. The capture stage includes a plurality of reference markers spaced apart by a predetermined distance. The reference markers are imaged with the capture device. A distance between the reference markers is measured. A correction difference between the measured distance of the reference markers and the predetermined distance is computed. An angular correction value based on the correction difference is computed. The angular position of the capture device relative to the capture stage is adjusted based upon the angular correction value.
