The present invention provides methods of electroplating a film or films onto a top surface of a sheet, preferably a continuously moving roll-to-roll sheet. In certain aspects of the invention, there are provided methods in which the molar ratio of the elements or thickness of the layers in a plurality of layers are detected so that tuning of the multi-element layer can occur to obtain the multi-element layer that has a predetermined molar ratio range or tuned thickness. In still another aspect, the invention includes continuously electroplating a film onto a conductive surface using an electroplating unit as the roll-to-roll sheet moves therethrough, detecting a thickness of the film electroplated onto a portion of the roll-to-roll sheet and generating a thickness signal corresponding thereto. In this aspect, when continuously electroplating, the thickness of the film is adjusted toward a predetermined thickness value using the thickness signal for a subsequent portion of the roll-to-roll sheet that follows the portion of the roll-to-roll sheet.
