Zebra GK420D Labels

Direct thermal labels use heat to produce an image on the label, while thermal transfer labels use a ribbon to transfer ink onto the label.

Direct thermal labels are typically used for short-term applications like shipping labels, receipts, and tickets.

Thermal labels can be water-resistant or waterproof depending on the materials used. It's important to select the correct label type for specific environments.

Traditional thermal printers typically print in black, but color thermal transfer labels can be printed with specialized color ribbons and thermal transfer printers.

Thermal labels should be stored in a cool, dry place, away from direct sunlight, heat, or humidity to prevent fading or degradation.
