How Chromix Works
What Is Dye Sublimation?
Dye sublimation is a printing process where heat and pressure are used to transform solid ink into a gas, which then permanently bonds with a specially coated surface.
Unlike regular printing where ink sits on top of a material, dye sublimation infuses the ink directly into the coating of the aluminium panel. The ink becomes part of the metal at a molecular level.
This is the same technology used by professional photographers, fine art galleries, and museum exhibitions worldwide. The result is unmatched colour vibrancy, detail, and durability.
How Your Metal Poster Is Made
Why Aluminium?
It's lighter than steel. A Chromix A2 piece weighs around 400g. Competitors who use steel panels produce heavier products that need screws and brackets to mount. Ours uses a simple magnetic pad.
It doesn't rust. Aluminium is naturally corrosion resistant. The panel itself can handle humidity, but we recommend mounting in dry, indoor spaces for the best adhesive bond. Kitchens, living rooms, bedrooms, offices, and gaming setups are all ideal.
It enhances colour. The polymer coating on our aluminium panels is specifically engineered to absorb ink more evenly than steel, producing sharper detail and more vivid colour.
It's sustainable. Aluminium is one of the most recycled materials on the planet. Over 75% of all aluminium ever produced is still in use today.
How to Mount Your Metal Poster
Clean the Wall
Wipe the wall surface with the included cleaning wipe. Make sure it's clean, dry and grease-free. Wait 3–5 minutes for the surface to dry completely before moving on.
Apply the Protective Leaf & Magnet
Peel the backing off the protective leaf and press it firmly onto the wall where you want your metal poster. Smooth out any air bubbles. Then peel the rubber magnetic sheet and press it firmly onto the centre of the protective leaf for 20 seconds. For best results, leave the mounting pad on the wall for a full 24 hours before hanging your piece — this lets the adhesive bond firmly.
Apply Iron Sheet to Your Metal Poster
Peel the backing off the iron sheet. Stick it onto the back of your Chromix metal poster, centred on the poster. This is what connects magnetically to the wall mount.
Hang Your Piece
Align the iron sheet on the back of your piece with the magnet on the wall. They'll click together and hold securely. To remove, swap, or reposition your piece, simply lift it off the magnet — no damage to your wall.
Recommended assembly temperature: 16°C – 39°C. Avoid uneven or textured walls — the smoother the surface, the better the hold.
Choose Your Size
Every size ships with a magnetic mounting kit. Every piece is printed on 1mm polymer coated aluminium.

| A4 | 210 × 297 mm | Desks, shelves, compact spaces |
| A3 | 297 × 420 mm | Above a shelf, bedside, small feature wall |
