Fiducial markers (reference marks and associated tracing codes) are applied to sheet materials such as electrodes, paper, plastics, and fabrics and serve as reference points along the machine direction. As the sheet advances, tracing codes are recorded to create a database of tracing codes and as a physical property of the sheet of material is measured a measurement profile is recorded wherein measurements of the physical property are synchronized with the tracing codes from the database so that different portions of the measurement profile are associated with one or more accompanying tracing codes. Customers can match measurements made during production to finished products such as electrochemical batteries so that defects found at a later stage of production can be traced to the source measurements to achieved improved quality assurance. The reference marks facilitate alignment among measurements made by different scanners.
