These premium paper labels use direct thermal printing technology which uses heat-sensitive media to blacken the label. Direct thermal printers have no ink, toner, or ribbon, making them cost-effective and easy to use. While these labels are recommended for a wide range of applications, including product and sample labeling, they are not recommended for lifetime identification due to the possibility of fading over time or overexposure to heat or light.
