Heat sublimation is one of the most popular methods for creating high-quality, durable images on aluminum sheet. Achieving perfect results depends heavily on using the right temperature and time during the heat transfer process. Here’s what you need to know.
Why Temperature and Time Matter
In metal printing, the sublimation ink turns into gas under heat and bonds with the special coating on the aluminum surface. If the temperature is too low or the time is too short, the colors will be faded or incomplete. Too high or too long, and the image may become blurred, discolored, or damage the coating.
Recommended Temperature for Sublimation Aluminum
Most sublimation aluminum panels perform best at:
Temperature: 180°C–200°C (356°F–400°F)
This range ensures the sublimation ink fully transfers while keeping the aluminum coating intact.
Recommended Time for Sublimation Aluminum
For standard 0.45–1.15 mm coated sublimation aluminum panels:
Time: 60–90 seconds (using medium pressure)
For thicker panels or high-gloss coatings, you may need up to 120 seconds to ensure full image transfer.
Quick Reference Table
| Panel Type | Temperature | Time | Pressure |
| Standard Panel | 180℃-200℃ | 60–90 sec | Medium |
| High-Gloss Panel | 180℃-200℃ | 80–120 sec | Medium |
Pro Tips for Best Results
- Preheat your press – ensures a stable temperature from the start.
- Use protective paper – prevents sublimation ink or coating damage.
- Test before bulk production – slight variations in coatings and inks may require adjustments.
Correct temperature and time are crucial for achieving vivid, long-lasting metal prints on aluminum. Staying within the recommended ranges will help you achieve consistent, professional-quality results every time.
