A method and a system for efficiently using media stamped on a substrate include a feedroller, a shuttle, a cylinder and a control arrangement. The media has at least one registration mark. The feedroller is coupled to the media and provides the media with a first velocity component. A shuttle is coupled to the feedroller via the media and moves linearly with a variable periodic velocity. The shuttle provides the media with a second velocity component, the second velocity component being a function of the velocity of the shuttle. A cylinder has at least one die and a stamping area in which one of the at least one die urges the media against a substrate. The media and the substrate have same velocity in the stamping area during the urging, but the substrate has a greater average velocity than an average velocity of the media. A control arrangement is coupled to the feedroller, the shuttle and the cylinder. The control arrangement maintains a registration between the media and substrate. The control arrangement detects a position of at least one of the at least one registration mark, the feedroller and the cylinder and modifies a gear ratio to reduce errors in the registration based upon the detected position. The gear ratio represents a ratio between a cycle on the media and a cycle on the substrate. |
