✅ 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.
