An adaptive overprint system for providing an overprint upon a substrate; the substrate comprising a plurality of registration markers at predetermined locations thereon and at least one pre-printed feature; the system comprising: an imager for capturing a digital image of said substrate with said registration markers and said feature; a printing platform upon which the substrate resides during overprinting; a printing mechanism for stamping said overprint upon said pre-printed feature; a controller operatively connected to said imager and said printing mechanism; and a handling device to move the substrate in and out of the printer; wherein said controller is adapted to identify and calculate the shift in said pre-printed feature based on said image of the substrate received from said imager, and to calculate a correlating compensation or correction shift to be electronically applied to the overprinted image. |
