Direct Thermal Label printers work by applying heat to the thermal print head, which activates the direct thermal media. Direct Thermal Labels are made from a heat-sensitive material which then turns the label dark where the heat is applied to create the image.Jul 22, 2017
What is a thermal tag?
Thermal labels use heat to create an image. Thermal transfer uses a thermal ribbon where heat from the printhead releases the ribbon attaching it to the label surface. Direct thermal images are created when heat from the printhead causes components on the label surface to mix causing them to (usually) turn black.
How long do direct thermal labels last?
Because it uses heat-sensitive materials, direct thermal labels do not have a long shelf-life, usually lasting around six to eight months. They have a tendency to scratch easily, and overexposure to direct sunlight or high temperatures will cause the print to fade faster.Jun 9, 2021
