Depending on the type of machine, a printer can be installed to print a 1D or 2D barcode, a logo, a date, a numbering… a unique identifier can be generated for each reel. Data can be entered manually or using a scanner. The exploitation of the printed data is possible thanks to a data file created either for each production batch or either for each product. The data are transferred on a 2nd PC, called "Data PC". They are available to the customer, who can use them in his own traceability system.
