UV DTF Transfers Press Settings for 100% Rayon
For UV DTF Transfers on 100% Rayon: press at 270-295F for 10-15 seconds with light-medium pressure, cold peel. UV DTF transfers use a UV-cured adhesive layer distinct from standard DTF. While 100% Rayon is not an ideal UV DTF substrate (UV DTF is designed for hard goods), this guide covers the edge cases where UV DTF encounters 100% Rayon surfaces in combination products.

Step-by-Step Pressing Process
- 1
Pre-press the fabric
Set your heat press to 270-285F. Press the substrate for 3-5 seconds without the transfer to remove moisture and flatten wrinkles. Gentle pre-press only. Rayon scorches easily. Keep pre-press under 5 seconds.
- 2
Position the transfer
Center the UV DTF Transfers on the fabric in the correct placement location. For apparel, use a heat-resistant tape or alignment ruler to verify placement before pressing.
- 3
Apply heat and pressure
Press at 270-295F for 10-15 seconds with light-medium pressure. Ensure the platen makes full, even contact with the transfer area.
- 4
Peel the carrier film (cold peel)
Wait 30-90 seconds for the transfer to cool completely to room temperature before peeling. Peeling while still warm on a cold-peel film will lift the design. When in doubt, wait longer.
- 5
Finish press
Place a Teflon sheet or parchment paper over the peeled design. Re-press at 270-285F for 5-8 seconds with light pressure. Use Teflon sheet. Very light pressure. Rayon shows press marks easily.

UV DTF-Specific Notes for 100% Rayon
UV DTF transfers use a UV-cured pressure-sensitive adhesive, which is distinct from standard DTF. 100% Rayon is primarily a textile substrate, which is not the designed use case for UV DTF. If UV DTF is being tested on this material, clean the surface with isopropyl alcohol and burnish firmly. Adhesion results will vary and are not guaranteed on fabric substrates.
Common Pitfalls on 100% Rayon
- Rayon is extremely heat-sensitive. Exceeding 295F can cause permanent scorching, fiber damage, and sheen changes.
- Too much pressure leaves permanent press marks — rayon does not recover from compression.
- Rayon can shrink under heat. Do not over-press.
- Some rayon dyes are reactive. Test on an inconspicuous area first.
Pro Tips for 100% Rayon
- Cold peel is safest for rayon. Let the transfer cool completely (60+ seconds) before peeling.
- If adhesion feels weak at 270F, increase time by 2-3 seconds rather than raising temperature.
- Use a pressing pillow inside the garment to prevent press marks and ensure even pressure.
- Rayon DTF transfers are achievable but require the most careful handling of any common fabric.
Frequently Asked Questions
What temperature should I use for UV DTF on 100% Rayon?
Press at 270-295F (132-146C). Start at the lower end of the range and increase only if adhesion test fails.
How long should I press UV DTF transfers on 100% Rayon?
Press for 10-15 seconds at light-medium pressure.
Hot peel or cold peel for UV DTF on 100% Rayon?
Cold peel is required for 100% Rayon. Wait at least 30-60 seconds after pressing before peeling the carrier film.
What are the most common mistakes when pressing UV DTF on 100% Rayon?
Rayon is extremely heat-sensitive. Exceeding 295F can cause permanent scorching, fiber damage, and sheen changes. Too much pressure leaves permanent press marks — rayon does not recover from compression. Tip: Cold peel is safest for rayon. Let the transfer cool completely (60+ seconds) before peeling.
