Ensure exceptional print quality with Westinghouse's Thermal Transfer Ribbons! Manufactured with a premium wax formula, our ink ribbons deliver sharp and clear thermal prints that are easy to read and scan - a great option for standard tags, labels, and high-density barcodes. Resin-enhanced for increased durability, providing scratch and smudge resistance as well as better print longevity compared to direct thermal methods. Our premium wax ribbons cater to a wide variety of applications, including - but not limited to - shipping labels, general ticketing, retail tags, RFID, inventory labeling, carton labeling, and more. They're perfect for small and large scale ecommerce businesses that engage in fulfillment and tracking! Our thermal transfer ribbons are also designed to be printed across a variety of label stocks, such as plain and coated paper as well as most flood-coated and matte synthetic paper.
