Direct Thermal vs. Thermal Transfer: What’s the Difference?

Direct thermal and thermal transfer methods both use heat to print, and both produce high-resolution images. Many modern printers from brands such as Zebra, Sato or Datamax even have the capability to print in either mode. But, each one has distinct advantages that make them best suited for different applications.

Direct Thermal

Instead of using ink or ribbons, direct thermal printers apply heat to label material coated with special chemicals. When the labels pass over the print head, selected areas turn black from the heat to create images. Since these printers have fewer components, they are easy to operate with fewer parts to maintain. They also are capable of printing high volumes in a short amount of time. But, since the label material is heat sensitive, sun and heat exposure will cause images to fade over time. This is why direct thermal labels are best for short-term needs that require the most efficient printing method.

Applications:

  • Barcodes and shipping labels
  • Name tags, visitor passes 
  • Event tickets
  • Receipts and pick tickets

Thermal Transfer

Thermal transfer printers use heated ribbons that hold ink to transfer images onto paper. Because the text or image is absorbed into the label stock, this method offers increased durability, and can withstand heat, UV light, and even chemicals. Thermal transfer printers also work with a variety of materials other than paper, such as plastic or plastic or polyester. Thermal transfer printing is ideal for labels that require long-term durability in harsh conditions.

Applications:

  • Asset tracking
  • Outdoor use
  • Tamper-resistant labels
  • Compliance labels
