Tek Code System is processing a wide range of supreme quality thermal transfer ribbons. These products are used for printing text and graphics onto a substrate. A wax- or resin-based ink that is coated on the ribbon is melted by the print head's heat and transferred to the substrate. Coated and uncoated labels and tags, general-purpose labelling, shipping labels, carton labelling, retail tags and labels, print and apply applications, and more are all approved for use with wax ribbon. Thermal transfer ribbons are a thin film that is wound on a roll and has a unique black coating on one side.
