📝 Step-by-Step Instructions
- Prepare Your Design & Aluminium
- Ensure your sublimation print is mirrored.
- CRITICAL: Most sublimation aluminium has a clear protective film on the coated side. YOU MUST REMOVE THIS FILM BEFORE PRESSING.
- Pre-Press the Aluminium (Recommended)
- With the protective film removed, briefly pre-press the aluminium for a few seconds. This helps remove moisture and ensures it's flat, especially in humid environments.
- Protect Your Setup & Position Materials
- Place protective paper (Silicon Paper recommended) on the bottom platen of your heat press.
- Lay the mirrored sublimation print face up on the protective paper.
- Position the aluminium item (coated side, film removed) face down onto the sublimation print.
- Secure with heat-resistant tape to prevent shifting.
- Place another sheet of protective paper on top of the back of the aluminium.
- Press & Monitor
- Press using the settings recommended above. Adjust time slightly based on aluminium thickness if experienced.
- Post-Press Care
- HOT! The aluminium will be VERY hot after pressing. Use heat-resistant gloves.
- Peel Immediately: Carefully remove the sublimation paper straight away while the item is still hot.
⚠️ Critical Safety & Success Tips
- FILM REMOVAL IS KEY: Double-check the protective film is removed. Failure to do so will result in a ruined print and residue on your press.
- Handle with Care: Aluminium will be extremely hot.
- Test Thickness: If working with various aluminium thicknesses, a quick test on a scrap piece can save material and ensure optimal results.
