Thermal Transfer Ribbons: A thermal ribbon is required to print on thermal transfer materials. There are basically three formulations available: Wax, Wax/Resin, and Resin. The formulation to use is based on the material of the facestock that is being printed. According to printer manufacturer specifications, the ribbon should always be slightly wider than the media on which you are printing.
The Chemical Resistant Resin formulation is recommended for use on thermal transfer labels and tags with polyester facestocks for use on chemical drums or in other harsh applications where the label or tag might come in contact with chemicals or solvents.
