I sublimated acrylic photo things, first try it did not warp but the second one did. How to press acrylic without warping? I don't want to waste any more blanks. Thank you !!!
Sublimating acrylic can be gorgeous when done right — but that warping? 😩 Been there, wasted that! Here's your step-by-step walkthrough to avoid the dreaded bend and save those precious blanks!
What Likely Happened
If your first acrylic blank turned out perfect and the second one warped, it's usually due to excess heat, too long of a press time, or lack of support during cooling. Acrylic is sensitive to heat, so small changes can cause major warps.
✅ Step-by-Step: How to Sublimate Acrylic Without Warping
- Preheat Press (but not too hot!)
Temp: 375°F (you can go as low as 360°F if warping is an issue)
Time: 60–70 seconds (not the usual 90!)
Pressure: Light to Medium — not heavy! Acrylic doesn't like pressure.
- Protect Your Blank
Remove any protective film from the sublimation side (usually one side is coated).
Place your sublimation design face-up, blank face-down on top.
- Build a Heat Sandwich 🥪
From bottom to top:
Heat-safe mat or Nomex pad (not metal if possible)
Blowout paper
Sublimation print face-up
Acrylic blank face-down (sublimatable side touching the paper)
Blowout paper on top
A firm, flat item on top (like a clean ceramic tile or flat MDF board) to help keep it pressed evenly during and especially after sublimating
- Immediately Cool Flat
As soon as it's done, remove it carefully (with heat gloves!) and place under a heavy, flat object (like a thick book or another tile).
Let it cool completely — acrylic holds heat and will warp if left unsupported.
✨ Pro Tips:
Don’t use Teflon sheets — they retain heat and cause overheating.
Sublimate one at a time for consistent results.
Acrylic can vary by brand, so test once and document your settings!
Hope this helps save your sanity and your supplies! You’ve got this! 💪

Sublimating on acrylic can be a magical way to preserve and display photos, but ensuring a smooth, warp-free finish requires a few careful steps.
Tips for Pressing Acrylic Without Warping
Use Moderate Heat
Acrylic is sensitive to high temperatures, so aim to use a moderate heat setting on your heat press (around 360°F to 375°F is generally recommended).
Adjust Press Time
Keep the pressing time short to minimize heat exposure. Start with about 60 seconds and adjust as necessary based on results.
Use Protective Paper
Place a sheet of butcher paper or parchment paper between your acrylic and the heat plate to help distribute heat evenly.
Cool Down
Allow the acrylic to cool slowly after pressing. You can place it on a cooling rack so that air circulates around it evenly, preventing warping.
Test Different Pressure Settings
Experiment with using lighter pressure, which reduces the stress on the acrylic during pressing.
With these adjustments, your acrylic pieces should come out perfectly smooth and beautiful. Happy sublimating! 😊
