WWX ribbon is a general purpose ribbon particularly adapted to standard label printing where good mechanical resistance is required. The ink provides an excellent print quality of picket and ladder barcodes, very small text, large characters, and logos. The ribbon structure allows printing on various label stock, such as coated and uncoated papers, and some synthetics. The printed ink offers improved smudge resistance compared to standard wax, and heat resistance up to 65° C (149° F). These characteristics remain at speeds up to 300mm/s (12 ips), and with 200, 300 and 600 DPI printheads. WWX features Wasp's outstanding backcoat technology ensuring excellent printhead protection, no clogging and prevents static build up.
