Are DNP thermal transfer ribbons UL-recognized?

UL approval 2

DNP thermal transfer ribbon inks have been found suitable for use with more than 60,000 different papers, films, and label materials as specified in UL's Certification Directory for Recognized Component Printing Materials.

  • Inks, such as thermal transfer ribbons, cannot be "UL-approved" by themselves because they are not considered usable until printed.
  • Only the printed ink is recognized by UL - for example, a specific thermal transfer ribbon formulation on a specific label material.
