The use of direct thermal labels has spread across various industries due to factors like their simplicity, cost-effectiveness, and ease of use. They help get rid of the need for ink, toner, or ribbons by using heat-sensitive paper that turns black when exposed to a thermal print head.
However, every good item still has its issue, and for thermal Labels, that issue is their susceptibility to fading over time. When left untended, the issue becomes problematic, especially in applications where labels need to remain legible for extended periods. So, the question of the day is, how do you prevent direct thermal labels from fading?
1. Always Pick High-quality Thermal Labels
One thing you should note is that not all direct thermal labels are created equal. Some labels have the luck of being made from higher-grade materials designed to resist fading better than others. One thing is certain: the quality of labels you choose plays a significant role in their longevity.
So when choosing thermal labels, look for those that are specifically formulated for long-term use, often labelled as “long-life” or “extended durability.” What’s also special about high-quality labels is that they are coated with protective layers that help them withstand environmental factors such as light, heat, and moisture, which are common culprits behind fading.
2. Ensure Optimal Storage Conditions
Choosing thermal labels of high quality won’t make any difference if those labels aren’t stored properly. In other words, optimal storage is crucial to preventing premature fading.
Failure to do so leads to issues like exposure to extreme temperatures, humidity, and direct sunlight, all of which can cause the thermal coating on the labels to deteriorate, leading to fading. So be sure to store them in a cool, dry place away from direct sunlight to prolong their lifespan.
3. Limit UV Light Exposure
One thing you may not know is that direct thermal labels are highly sensitive to ultraviolet light, so long exposure can cause rapid fading. So, what you’ll need to do is minimise UV exposure. Avoid placing labelled items in direct sunlight or under strong artificial lighting.
In cases where exposure to light is unavoidable, consider using a protective covering or storing the items in opaque containers to shield them from UV rays.
4. Ensure the Labels Have Laminates and Protective Coatings
If you want to keep your labels free from rapid fading, do well to laminate them or apply a protective coating. Adding laminates adds a clear, adhesive layer that covers the label, providing a barrier against environmental factors such as moisture, abrasion, and light.
On the other hand, protective coatings, which can be applied as a spray or liquid, serve a similar purpose by adding a durable layer over the label. This particular solution is one you shouldn’t overlook because labels are always exposed to harsh conditions, such as shipping, handling, or outdoor uses.
Conclusion
If you want to prevent direct thermal labels from fading, you need to be attentive to a lot of details. From selecting the best label materials to providing optimum storage conditions, there are standard preventive measures that help prolong the lifespan of direct thermal labels.
When you follow the steps above diligently, you ensure the direct thermal labels remain legible, maintaining their effectiveness in any application. Finally, whatever you’re using the labels for, preventing them from fading is crucial to maintaining the integrity and reliability of your labelling system.
