🔥 Oven Heat Press Settings

Temperature: –180°C
Time: 200–360 seconds
Pressure: Heat Shrink (Add 10-20s for each additional substrate in the oven)

📝 Preparation

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

🛠️ Oven Baking

1. Heat the oven to required temperature.
2. Apply heat shrink and heat or apply silicone clamp.
3. Place substrate/s in the oven.
4. Position the substrate inside the oven.
5. Bake at listed Heat Press Settings Above.
6. In some air fryers, you may need to rotate half way through baking due to insufficient air flow.

7. Remove carefully from oven after timer has finished. (Caution: Will be extremely hot.)

❄️ 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.

4. Remove adhesive cover from tumbler base and apply to the centre of the substrate. (If applicable)
5. Attach lid.
6. Wrap in protective plastic cover and place into packaging.

✅ 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.
• Screw lid on and pay attention the where the straw will be located, align the main focus point of the print to the this area.
• When taping the seam, tape with high pressure applied to the print ensuring tightness.
• Do not press with lid or base attached.
• Trim heat shrink to not have too much excess overhanging, it is hard to remove.
