Direct thermal labels are printable labels that use heat to create an image as opposed to other labels that use light or electricity. This process is more cost effective than different label types and decreases the risk of damaging the product with chemicals or other elements.
Direct thermals are similar to standard thermal labels in that they are printed with a heat-sensitive coating and respond to heat by changing their appearance. However, direct thermals use a different printing mechanism to achieve this effect. Rather than using an electromagnetic ink or thermochromic dye like standard thermal labels, direct thermal labels use a special kind of ink that changes color when heated. Follow along to learn more about these labels.

Direct thermals work just like traditional thermal labels in that they have a heat-sensitive coating that changes color when the label is exposed to heat. The underlying technology is different, however.
Direct thermals use ink instead of ink and dye or pigment. That means that direct thermals are more colorful and brighter than other labels, but they also require a particular printer and special paper to achieve good results.
Features and Benefits of Direct Thermal Labels
Direct thermal labels are a more expensive label solution than standard thermal labels, but they often offer a better-looking, brighter label with more vibrant colors.
Direct thermals use ink that is different from traditional thermochromic inks. That means that direct thermal labels can be printed on plain paper and have a cleaner, crisper appearance than the standard thermochromic inks used in other thermal labels.
Direct thermals look good when printed on plain paper because they have more vivid colors and richer blacks than standard thermochromic inks can achieve without special paper.
Unlike typical thermochromic products, direct thermal products by Zebra tend to contain less toxic pigments, making them safer for use around workers and the environment.
Direct-thermal printing technology is not currently used for all types of promotional products, but it has been used by many businesses to print personalized signs and labels. From name badges to event invitations and stickers, direct-thermal printing offers a distinctive look that your customers will immediately notice.
Advantages of Direct Thermal Labels
• Direct thermals are safer for your employees. They are also not as prone to fading or smudging as standard thermochromic inks, which last much longer than traditional thermochromic labels.
• Direct thermal signs are also more durable, meaning you can use them for several years without worrying about them wearing out too quickly.
• Because direct thermals do not contain pigments, they do not require hazardous waste disposal procedures and can be printed on any plastic or glass surface.
• Zebra’s direct-thermal products include everything you need to create personalized signs and labels, from high-quality thermal ink in bottles and trays (available in various colors) to the necessary application equipment.
• All labels feature a high-quality, preshrinkable surface coated with environmentally safe thermoplastic ink resistant to most common solvents and UV rays.
• A 5-year warranty backs all the direct-thermal labeling equipment manufactured by Zebra, meaning it will perform flawlessly. That is even under harsh conditions like extreme temperatures or when used on non-porous substrates, such as glass and plastic.
• Direct-thermal application solutions by Zebra include temperature sensors, printers, and accessories. That way, you can print direct-thermal labels on any surface (transparent or opaque), including signs made of plastic or glass, magnetic signs, and more.
• Some labels are compatible with most third-party applications for printers, including AutoCAD Civil 3D and many other CAD/CAM software brands. It pairs with your Android or Apple mobile device using Bluetooth technology to allow printing from your smartphone or tablet. You must use a cable for direct-thermal printing if you want to use it with your Windows or Mac computer.
• Direct thermals are also excellent for scrapbooking, professional photography and video production, and other artistic projects requiring printed text in various colors.
Zebra also makes many accessories like thermal coping, self-adhesive pads, labeling trays, printers with integrated screen overlays (ADF), and more.
