📝 Preparation

1. For templates, Mock-ups and image size required, please refer to the Design tab.
2. Print your design, MIRROR your image.
3. Remove the protective cover from the sublimation surface.
4. Clean the substrate printing surface using a microfiber cloth or lint brush to remove dust, oils or lint. (As per substrate)
5. Place the printed image face up and align the subatrate to the centre of the print.
6. Secure the edges using heat-resistant tape to prevent movement.

🛠️ Flat Heat Press Pressing

1. Place a sheet of protective paper on the press.
2. If this is your first press of the day, make sure you do a pre-press at the suggested heat press settings and bring all materials up to temperature.
3. Flip the substrate holding the taped areas to secure.
4. Place the substrate into the press sublimation coating face down, away from the heating element.
5. Cover with another sheet of protective paper.
6. Press at listed Heat Press Settings Above.

❄️ Cooling and Assembly

1. Carefully remove the substrate from the press (it will be hot).
2. Peel off the sublimation paper while the substrate is warm for best results.
3. Allow the substrate to cool completely.
4. Remove the adhesive backing from the Phone Case Cover.
5. Align and affix the aluminium insert firmly onto the Phone Case Cover.

✅ 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.
• Warm the adhesive on the case by hovering the heat press over the case after removing the cover for 10–20 seconds before applying the insert. (Not Included)
