1. A method for aligning plurality of imaging systems for capturing images of a receiver medium, comprising: using an illumination system to illuminate the receiver medium with light providing an illumination pattern; using a first imaging system to capture a first image of the receiver medium, the first image including at least a portion of the illumination pattern; using a second imaging system to capture a second image of the receiver medium, the second image including at least a portion of the illumination pattern; using a data processor to automatically analyze the captured first and second images to determine a relative position of the illumination pattern in the first and second images; determining one or more imaging system alignment parameters responsive to the determined relative position; and storing the determined imaging system alignment parameters in a processor-accessible memory for subsequent use in aligning images captured with the first imaging system with images captured with the second imaging system.
