Sublimation on aluminum is one of the best ways to create durable, colorful, and professional prints. Whether you want to make photo panels, signage, nameplates, or promotional products, aluminum sublimation sheets give excellent results. In this guide, we will explain how to sublimate aluminum, what equipment you need, and how to choose the right size, coating, and alloy.
What Is Aluminum Sublimation?
Aluminum sublimation is a printing process where special sublimation ink is transferred onto a coated aluminum sheet under high temperature and pressure. The ink turns into gas and bonds with the polyester coating of the aluminum surface. This creates:
- Bright and vibrant colors
- Scratch resistance
- Long-lasting durability
- Smooth glossy or matte finish
Step-by-Step: How to Sublimate Aluminum
Here is a simple process you can follow:
| Step | Action | Details |
|---|---|---|
| 1 | Prepare the sheet | Clean the aluminum sublimation sheet with a lint-free cloth |
| 2 | Print the design | Use sublimation paper and sublimation ink |
| 3 | Position | Place the printed paper face down on the coated side of the aluminum |
| 4 | Heat press | Apply 180–200°C (356–392°F) for 50–60 seconds |
| 5 | Cool down | Remove paper carefully and let the sheet cool |
Choosing the Right Aluminum for Sublimation
Not all aluminum sheets are the same. When selecting, you should consider:
- Coating: Must be polyester coated for sublimation.
- Alloy: Common alloys include 1050, 1060, and 1100.
- Thickness: Depending on use, from 0.5mm up to 1.5mm.
- Finish: Glossy, matte, brushed, or white.
Common Specifications
| Type | Thickness (mm) | Alloy | Finish | Applications |
|---|---|---|---|---|
| Standard sheet | 0.5 | 1050 | Glossy white | Photo panels, tags |
| Medium sheet | 1.0 | 1060 | Matte | Signs, nameplates |
| Heavy sheet | 1.5 | 1100 | Brushed | Industrial plates |
Applications of Sublimated Aluminum
Sublimated aluminum is widely used in both commercial and personal projects.
- Photo panels and wall art
- Custom signage
- ID cards and nameplates
- Awards and trophies
- Promotional items
- Labels and tags
- Decorative panels
Materials Needed for Aluminum Sublimation
Before you begin to sublimate aluminum, gather all the necessary tools and supplies. Having everything ready will make the process smooth and enjoyable.
| Item | Description |
|---|---|
| Sublimation Printer | A printer specifically designed to use sublimation inks. Standard inkjet printers will not work. |
| Sublimation Ink | Special dyes that turn into gas when heated. |
| Sublimation Paper | Paper designed to hold and release sublimation ink efficiently during heat transfer. |
| Blank Sublimation Aluminum Panels | Aluminum sheets with a polymer coating ready to accept sublimation dyes. Available in various sizes and finishes. |
| Heat Press Machine | Essential for applying consistent heat and pressure. Flatbed presses are common for aluminum. |
| Heat-Resistant Tape | Used to secure the printed design to the aluminum blank, preventing “ghosting.” |
| Protective Paper | Parchment paper, butcher paper, or silicone sheets to protect your heat press platens from ink transfer. |
| Heat-Resistant Gloves | To safely handle hot aluminum after pressing. |
| Lint-Free Cloth | For cleaning the aluminum surface before pressing. |
| Cleaning Solution | Isopropyl alcohol or a mild degreaser to ensure the aluminum is free of oils and dust. |
Tips for Perfect Sublimation on Aluminum
- Always use high-quality sublimation ink and paper.
- Make sure the sheet has a polyester coating.
- Preheat your press to remove moisture.
- Use even pressure across the sheet.
- Test with small samples before bulk production.
FAQ: How to Sublimate Aluminum
Q1: Can I sublimate on any aluminum sheet?
No. Only polyester-coated aluminum sheets work with sublimation.
Q2: What temperature should I use for sublimating aluminum?
The standard is 180–200°C (356–392°F) for 50–60 seconds.
Q3: What kind of printer do I need?
You need a sublimation printer with sublimation ink, not a regular inkjet.
Q4: Can sublimated aluminum be used outdoors?
Yes, but for long exposure to sun or rain, choose UV-resistant coated aluminum sheets.
Q5: What thickness of aluminum sheet is best?
For photos and small products: 0.5mm. For signage: 1.0mm. For heavy-duty plates: 1.5mm or more.
