Wax ribbons work best with paper matierlas when fast print speeds are required, and in applications with little to no exposure to chemicals or abrasion. The 5319 performance wax thermal transfer ribbon is a custom wax ink formulation that produces high-quality normal and rotated bar codes on coated and uncoated paper at print speeds up to 8 ips. Produces a crisp black image with excellent high-speed performance and outstanding visible light and infrared scannability. Ideal for general purpose, high-density barcode and text printing on paper label stocks. Especially recommended for printing rotated (ladder) bar codes, high resolution graphics and fine text characters
