Thermal Transfer vs. Direct Thermal Labels: Choosing the Right Self-Adhesive Solution for Logistics
1. How Thermal Labels Work
Thermal labels rely on heat-activated printing:
Direct Thermal (DT): Heat darkens the label’s coated surface (no ink/ribbon required).
Thermal Transfer (TT): A heated print head melts ink from a ribbon onto the label.
2. Key Differences Between DT and TT Labels
| Ciri | Direct Thermal (DT) | Thermal Transfer (TT) |
|---|---|---|
| Ketahanan | Fades under UV/heat | Long-lasting, resistant to fading |
| Cost | Lower upfront cost (no ribbon) | Higher (requires ribbons) |
| Best For | Short-term use (e.g., shipping labels, receipts) | Long-term tracking (e.g., warehouse labels, outdoor use) |
| Print Quality | Good for basic barcodes | Superior for high-resolution barcodes & logos |
3. Top Applications in Logistics
✅ Direct Thermal Labels:
Short-term shipping labels
Indoor barcode labels (e.g., retail, parcel tracking)
Expiration-date labeling (if not exposed to heat)
✅ Thermal Transfer Labels:
Long-lasting warehouse bin labels
Outdoor logistics labels (weather-resistant)
Compliance labels (hazardous materials, GS1 standards)
4. Choosing the Right Material
DT Labels: Typically use heat-sensitive paper (economical but less durable).
TT Labels: Can print on polyester, polypropylene, or vinyl for extreme conditions.
5. Best Practices for Thermal Label Printing
✔
Use high-quality thermal printers
(Zebra, Honeywell, Brother).
✔
Test barcode readability
(ISO/IEC 15416 compliance).
✔
Store DT labels away from heat/sunlight
to prevent premature fading.
✔
For TT, choose the right ribbon
(wax, wax-resin, or resin for durability).
Kesimpulan
Thermal self-adhesive labels improve logistics efficiency, but choosing between direct thermal dan thermal transfer depends on durability needs, cost, and environmental factors. While DT is ideal for short-term use, TT offers superior longevity for harsh conditions.
