Direct thermal labels are printed without a ribbon – the image forms on heat-sensitive paper. They are cheaper to run and convenient, but the print fades or darkens over time. Thermal transfer labels are printed with an ink ribbon – the print lasts for years and resists abrasion, sunlight and chemicals. Choose direct thermal for shipping labels and short-term marking, and thermal transfer for long-term marking, products and harsh conditions.
Direct thermal paper has a heat-sensitive layer that darkens when heated. The print head heats the paper dot by dot to create text, barcodes or graphics. There is no ink, toner or ribbon – only the label roll. That is why direct thermal printing is the simplest to use and the most common choice for shipping, scale and warehouse labels.
The same mechanism is also its limitation: the heat-sensitive layer also reacts to heat, sunlight (UV), friction and some substances (e.g. oils, alcohol, plasticisers from films). That is why we make two kinds of thermal paper:
See the comparison on the ECO and TOP thermal labels page.
In thermal transfer printing the head heats an ink ribbon and the ink transfers onto the label. The label does not have to be heat-sensitive – it can be paper, PP, PE or PET film. The print is durable and does not darken in sunlight. Durability depends on the ribbon:
| Ribbon | Label materials | Print resistance |
|---|---|---|
| Wax | Uncoated and semi-gloss paper | Basic – can be rubbed off with strong friction |
| Wax-resin | Coated paper, PP and PE films | Good – resists abrasion and moisture |
| Resin | PET, PP, PE films, industrial labels | Very high – resists chemicals, heat and abrasion |
The ribbon must match the label material and the printer (width, ribbon core, ink side). When you order labels, we advise which ribbon to use.
| Feature | Direct thermal | Thermal transfer |
|---|---|---|
| Ink ribbon | Not needed | Required |
| Print durability | From a few months (ECO) to longer with TOP paper and good storage | Years – with the right ribbon |
| Sunlight and heat resistance | Low – paper darkens | High |
| Abrasion resistance | Low (ECO), good (TOP) | High (depends on ribbon) |
| Materials | Thermal paper only | Paper, PP, PE, PET films |
| Printer handling | Simplest – label roll only | Ribbon selection and changes |
| Typical uses | Shipping, warehouse and scale labels, receipts | Product, asset, industrial and outdoor labels |
The heat-sensitive layer cannot tell whether heat comes from the print head or anywhere else. A thermal label darkens in sunlight, near a radiator or in a hot car, and grey streaks appear where it is rubbed. Contact with some plastics, oils or alcohol can make the print fade. How to prevent it:
Look at the printer model. On Zebra printers the letter “d” at the end (e.g. GK420d, ZD220d) means direct thermal, and “t” (e.g. GK420t, ZD421t) means a thermal transfer printer that can usually print on direct thermal paper without a ribbon too. Industrial printers (e.g. Zebra ZT411) usually support both modes. Other brands use similar markings – if in doubt, send us the printer model. Labels for Zebra printers – roll specifications
With direct thermal you don't buy ribbons, so the cost per print is usually lower and the printer is simpler to use. Thermal transfer needs a ribbon but gives a durable print and lets you print on films. The choice should mainly depend on how long and in what conditions the label must stay readable.
On ECO paper the print is intended for a short time, e.g. for the duration of a shipment. TOP paper with a protective coating stays readable longer, especially when stored in a dark, cool place. If the marking must last for years, thermal transfer is the better choice.
Usually yes – thermal transfer printers (e.g. Zebra models ending in t) also have a direct thermal mode. Just remove the ribbon and change the media type setting in the printer driver.
Yes. We produce direct thermal ECO and TOP labels and paper and film thermal transfer labels on rolls, in any size, with core and winding matched to your printer.
Send the label size, approximate quantity and what the labels are for – we will prepare a quote and email it to you. No obligation. Don't know all the specs? Describe the use and we'll advise.
