Direct thermal vs. thermal transfer printing
The two label printing techniques: directly on heat-sensitive paper, or via a ribbon onto the label.
Last updated:
Almost all label printers work with heat, but in two ways. Direct thermal prints straight onto heat-sensitive paper: the printhead heats the material and it turns black. Thermal transfer uses a ribbon whose ink is transferred onto the label by the heat.
Direct thermal is cheaper to run (no ribbon) and fine for short-lived labels: shipping labels, receipts, fresh-produce stickers. The downside: the print fades with sunlight, heat, and friction. A direct thermal label that must stay readable for months is the wrong choice.
Thermal transfer gives a durable, scratch- and chemical-resistant print and is the standard for product labels, pharma and chemical labels, and anything that has to survive outdoors or in a freezer. The ribbon choice (wax, wax/resin, or resin) together with the label material determines durability. Not sure which combination fits, or whether Loftware Cloud supports your printer?

Frequently asked questions — Direct thermal vs. thermal transfer printing
What is the difference between direct thermal and thermal transfer printing?
Direct thermal prints straight onto heat-sensitive paper (no ribbon); thermal transfer uses a ribbon whose ink is transferred onto the label by heat.
When do I choose thermal transfer?
For a durable, scratch- and chemical-resistant print: product labels, pharma and chemical labels, and anything that must survive outdoors or in a freezer.
Why does my direct thermal label fade?
Direct thermal paper fades from sunlight, heat and friction; it is meant for short-lived labels such as shipping labels and receipts.
