Thermal transfer ribbons are used with thermal barcode label printers to print barcodes other useful information on thermal transfer labels. The ribbons contain ink that is absorbed into the label material to form a crisp image during printing. Wax ribbons create smudge-resistant images and are suitable for labels that will be used in indoor environments where they will not be exposed to abrasion, harsh chemicals, or sunlight, such as retail stores or warehouses. Wax/resin ribbons create labels that resist smudges, weather, and scratches. They are suitable for use in indoor or outdoor environments where they may be exposed to light moisture or moderate abrasion. Resin ribbons resist smudges, scratches, abrasion, chemicals, and heat.
