Sublimation on Metal Temperature is a heat transfer printing process where special sublimation ink turns into gas and bonds with the polymer coating on a metal sheet. This method produces vivid, durable, and fade-resistant images on aluminum and other coated metals.
Sublimation metal products include:
- Photo panels
- Nameplates
- Trophies
- Signboards
- Custom metal gifts
How to Sublimate on Metal
To get the best print results, follow these simple steps:
| Step | Description | Recommended Setting |
|---|---|---|
| 1. Prepare the metal | Use a clean, coated metal sheet for sublimation | Surface should be free of dust or oil |
| 2. Print the image | Print your design using sublimation ink on transfer paper | Mirror image required |
| 3. Align the print | Place printed paper on top of the metal face-down | Fix with heat tape |
| 4. Press the metal | Use a flat heat press machine | 190°C – 200°C (375°F – 400°F) |
| 5. Cool and remove | Allow the metal to cool before peeling | Prevents ghosting or smudging |
Sublimation Heat Press Temperature for Polyester and Metal
The heat press temperature and time vary depending on the substrate type and coating thickness.
| Material | Temperature (°C) | Time (Seconds) | Pressure |
|---|---|---|---|
| Aluminum sheet (white coating) | 190 – 200 | 50 – 60 | Medium |
| Silver glossy aluminum | 190 | 45 – 55 | Medium |
| Polyester fabric | 200 | 35 – 45 | Light |
| Steel plate (polymer-coated) | 195 | 60 – 70 | Medium-high |
Tip: Always preheat the metal for 5 seconds to remove moisture and prevent blurring.
Sublimation Heat Press Settings
To achieve sharp, color-rich prints:
- Temperature: 190°C – 200°C
- Time: 50 – 60 seconds
- Pressure: Medium (avoid excessive force)
- Cooling: Let the metal cool naturally on a flat surface
Common issues:
- Faded colors → too low temperature
- Yellow tint → too high temperature
- Blurry edges → overpressing or misalignment
Can You Sublimation Print on Metal?
Yes. You can sublimate on specially coated aluminum sheets or metal panels that have a polymer coating.
Bare metal won’t absorb sublimation ink because it lacks a coating.
Suitable metals for sublimation:
- Aluminum
- Stainless steel (with coating)
- Chromaluxe panels
How Long to Press Metal Sublimation Signs?
Most metal sublimation signs require 50 to 60 seconds at 190°C to 200°C with medium pressure.
| Metal Type | Press Time (sec) | Temperature (°C) |
|---|---|---|
| White Aluminum | 55 | 195 |
| Silver Aluminum | 50 | 190 |
| Gold Aluminum | 60 | 200 |
Avoid overpressing — too much heat can cause ink bleeding or color fading.
Is an Iron Hot Enough for Sublimation?
No. A household iron cannot reach or maintain the precise temperature (190°C–200°C) required for sublimation.
Use a heat press machine instead for:
- Accurate temperature control
- Even pressure distribution
- Consistent image quality
How Long to Sublimate on 50/50 Fabric?
For 50/50 cotton-polyester fabric, sublimation is possible but colors appear lighter since only the polyester fibers hold the ink.
| Fabric Type | Temperature (°C) | Time (sec) | Result |
|---|---|---|---|
| 100% Polyester | 200 | 40 | Bright colors |
| 50/50 Cotton-Poly | 200 | 45 | Softer, pastel effect |
| 100% Cotton | — | — | Not suitable for sublimation |
Applications of Metal Sublimation Printing
Metal sublimation printing is ideal for both personal and commercial uses:
- Home decoration: Custom photo panels, wall art
- Advertising: Nameplates, door signs, displays
- Industrial use: Control panels, product labels
- Promotional items: Awards, trophies, souvenirs
Common Sublimation Metal Sheet Sizes
| Size (inch) | Thickness (mm) | Finish Options |
|---|---|---|
| 8×10 | 0.5 | Glossy, Matte |
| 12×18 | 0.8 | White, Silver |
| 16×20 | 1.0 | Brushed, Gold |
| Custom | 0.5–1.2 | UV-protected coating |
Sublimation on Metal Temperature
Understanding the correct sublimation on metal temperature is essential for perfect results. Maintain a consistent 190°C–200°C with 50–60 seconds press time to get vivid and durable prints.
Whether you’re printing photo panels, signs, or metal tags, correct heat settings will ensure sharp, colorful, and long-lasting images on your sublimation metal sheets.
Troubleshooting Temperature Issues
Common problems and solutions with sublimation on metal temperature:
Problem-Solution Table:
| Problem | Cause | Solution |
|---|---|---|
| Faded Colors | Temperature too low | Increase 5-10°F |
| Brown Spots | Temperature too high | Decrease 5-10°F |
| Blurry Image | Uneven pressure | Adjust pressure settings |
| Ink Transfer | Wrong time setting | Adjust pressing time |
Best Practices for Consistent Results
Achieve perfect results with these sublimation heat press settings tips:
- Pre-test Settings: Always test on small pieces first
- Use Timer: Precise timing is crucial
- Check Temperature: Verify with infrared thermometer
- Even Pressure: Ensure consistent pressure across surface
- Record Settings: Keep notes of successful combinations
Safety Considerations
Working with sublimation on metal temperature requires safety awareness:
Safety Checklist:
- Wear heat-resistant gloves
- Work in well-ventilated area
- Keep flammable materials away
- Use press on stable surface
- Don’t leave press unattended
Frequently Asked Questions
Q: What is the ideal sublimation on metal temperature?
A: 400°F (204°C) works best for most metal sublimation projects.
Q: Can you use the same temperature for all metals?
A: Most coated metals work at 400°F, but always test as some may need 5-10°F adjustments.
Q: How long to press metal sublimation signs for outdoor use?
A: 60-75 seconds at 400°F ensures deeper ink penetration for outdoor durability.
Q: Is an iron ever suitable for metal sublimation?
A: No, irons cannot provide the consistent temperature and pressure needed for quality metal sublimation.
Q: What happens if temperature is too high?
A: Overheating can yellow the coating, cause bubbling, or create brown spots on your design.
