To print on a pre-printed disc, ImageAligner is first "trained" to recognize the image of that disc. The camera mounted over the printer takes a snapshot of the disc to be imprinted with the text. This image appears on-screen along with a control to rotate the image to its proper orientation. The ImageAligner software rotates the text to be printed on the disc to exactly match the orientation of the disc in the printer. The result is great looking printed discs every time.
