Ideal Temperature and Time for Sublimating Aluminum
The sublimation temperature and time depend on the type of coating and thickness of the aluminum sheet. Below is a general guideline:
| Coating Type | Temperature | Time | Pressure |
|---|---|---|---|
| White Glossy | 190°C – 200°C | 60 – 70s | Medium |
| White Matte | 190°C – 200°C | 60 – 70s | Medium |
| Silver Brushed | 200°C – 205°C | 75 – 85s | Medium |
| Gold Coated | 200°C – 205°C | 75 – 85s | Medium |
💡 Pro Tip: Always pre-press your aluminum blank for 5–10 seconds to remove moisture before sublimation.
Sublimation Process Overview
Here is a step-by-step process to sublimate aluminum sheets:
- Prepare your artwork using sublimation design software.
- Print the design on sublimation paper with sublimation ink.
- Place the paper face down on the coated side of the aluminum.
- Apply heat press with correct temperature, time, and pressure.
- Remove the paper carefully and let the panel cool.
Applications of Sublimated Aluminum Panels
Aluminum sublimation sheets are ideal for high-resolution image printing. Their applications include:
- Photo panels and wall art
- Personalized signage
- Nameplates and plaques
- ID cards and metal business cards
- Custom gifts and promotional items
- Award and recognition plaques

Best Practices for Sublimating Aluminum
To ensure high-quality output:
- Always use high-quality sublimation ink and transfer paper.
- Clean the surface with a lint-free cloth before pressing.
- Use protective Teflon sheets or parchment paper to avoid ghosting.
- Test small samples before full production.
- Keep humidity and room temperature stable.
Common Issues and Troubleshooting
| Problem | Cause | Solution |
|---|---|---|
| Faded Colors | Low temperature or short pressing time | Increase time or temp slightly |
| Ghosting or Blurry Edges | Paper shifted during pressing | Use heat-resistant tape |
| Yellowing on surface | Overheating | Reduce temperature/time |
| Uneven Color | Uneven pressure or dirty surface | Clean surface and adjust pressure |
Why Choose Aluminum for Sublimation?
Aluminum is the ideal substrate for sublimation because of its:
- Smooth coated surface
- High heat resistance
- Excellent image clarity
- Durability and corrosion resistance
Whether for personal projects or commercial production, aluminum sublimation blanks provide long-lasting and professional results.
