What Is Metal Sheet Sublimation Printing?
Metal sheet sublimation printing is a heat transfer process that embeds images, designs, or text into a coated metal surface—usually aluminum.
Unlike surface printing, sublimation ink turns into gas and bonds permanently with the metal coating.
This creates vivid, long-lasting, and scratch-resistant prints that do not fade easily.
Commonly used metals:
- Aluminum sheets (most popular)
- Coated steel plates
- Stainless steel panels (with sublimation coating)

Metal Sublimation Printing Machine
A metal sublimation printing machine is a heat press or flatbed designed to transfer sublimation ink onto metal surfaces.
It ensures even temperature and pressure for consistent color output.
| Machine Type | Use Case | Feature |
|---|---|---|
| Flat heat press | Small sheets (A4–A3) | Ideal for photo panels |
| Pneumatic press | Large format sheets | Even pressure distribution |
| Vacuum press | Curved or shaped metal | Suitable for signs and tags |
Dye Sublimation Printing Process on Metal
Dye-sublimation printing on metal involves transferring images from sublimation paper to a specially coated aluminum sheet under heat and pressure.
Steps:
- Print your design with sublimation ink on transfer paper.
- Place the paper on the coated metal surface.
- Heat press at 190°C–200°C for 50–60 seconds.
- Remove and let it cool — the image becomes part of the metal coating.
Result: Bright, waterproof, and durable prints perfect for photos, signage, and art displays.

Can You Sublimate on Sheet Metal?
Yes. You can sublimate on sheet metal only if it has a polyester sublimation coating.
Bare metals (like untreated aluminum or steel) will not absorb sublimation dyes.
Therefore, always use pre-coated sublimation blanks for the best printing results.
How to Make a Sublimation Metal Sheet
If you want to prepare your own sublimation sheet:
- Choose a flat, clean aluminum or steel plate.
- Apply a special polyester sublimation coating evenly.
- Cure it at high temperature (150–170°C).
- Cool it completely before sublimation.
(Note: Industrial coating ensures best color adhesion — buying pre-coated sheets is more reliable.)
What Is Sublimation Metal?
Sublimation metal refers to aluminum or steel sheets coated with a special polymer that allows sublimation ink to bond permanently.
These sheets are ideal for printing high-resolution graphics that are scratch-resistant, waterproof, and UV-stable.
Can I Sublimate on Steel?
Yes, but only if the steel has been pre-treated with a sublimation coating.
Standard stainless steel does not work with sublimation ink because it lacks the polymer layer.
Coated steel sheets, however, are a strong and affordable option for signage and industrial labels.
