If you would like to put bar code labels on your products yourself, then you need to know there are two basic techniques. A standard label printer uses thermal printing to burn the ink in. The thermal transfer technique uses an ink ribbon. If the bar code needs to last a very long time, this technique gives the best result. When choosing a printer, it is also important to identify which material you want to use for your labels. CN Rood will gladly inform you about the options available.
