For the Weatherproof Thermal Transfer (TW) material we recommend using a Durable Wax Resin ribbon. These are ideal for synthetic materials like the polyester-based weatherproof option. Our Resin-Enhanced Wax ribbons are recommended for the paper-based materials like our Standard White Thermal Transfer.
