4. Clean the substrate printing surface using a microfibre cloth or lint brush to remove dust, oils or lint.
5. Place the substrate with the coated / printable side facing down.
6. Secure the edges using heat-resistant tape to prevent movement.

🛠️ Flat Heat Press Pressing

1. Set the heat press to the listed flat press settings.

3. Position the substrate and transfer correctly on the press.
4. Cover with another sheet of protective paper.

❄️ Cooling and Assembly

1. Carefully remove the substrate from the press (it will be hot).

3. Allow the substrate to cool completely.
4. Attach or reassemble any internal mechanisms, lids or parts if applicable.

✅ Tips for Best Results

• Ensure full edge-to-edge coverage in your design to avoid white borders (ensure bleed is sufficient).
• If colours look dull, increase time by 5 seconds or pressure slightly.
• If the coating looks yellowed, your temperature is too high or time too long.
• Store substrate in a clean, dry, dust-free area before printing.
