Sublimation Materials Guide Time, Temperature & Tips
Starting settings and practical tips for sublimation blanks, fabrics, drinkware, coated materials and heat press workflows.
Important: All time, temperature and pressure settings in this guide are starting points only. Sublimation blanks, coatings, inks, paper, heat presses, pressure, room conditions and product batches all vary. Always test before full production.
Sublimation printing works best when the correct time, temperature and pressure are matched to the material being printed. While sublimation is extremely versatile, each material behaves differently under heat, and small adjustments can make a big difference to final quality.
This sublimation materials guide provides practical starting settings and production tips for common sublimation materials. Use it as a baseline, then fine-tune based on your own press, paper, ink, coating quality and environment.
Before using any sublimation settings
Sublimation settings are not universal. Two presses set to the same displayed temperature may behave differently, and two blanks from different suppliers may have different coating quality. Always treat settings as a controlled starting point rather than a guarantee.
Variables that affect results
- Heat press accuracy and evenness
- Actual surface temperature
- Pressure and contact area
- Sublimation paper release quality
- Ink and ICC profile
- Blank coating quality
- Moisture and humidity
Signs settings need adjustment
- Dull colours
- Ghosting or blurred edges
- Scorching or yellowing
- Warping or surface distortion
- Faded areas or poor transfer
- Cracking or coating failure
- Uneven colour or pressure marks
Quick sublimation settings table

Sublimation fabrics and textiles
Polyester fabric
190°C • 45–60 seconds • Light–medium pressure- Higher polyester content gives stronger colour.

Frequently asked questions about sublimation material settings
Are sublimation time and temperature settings universal?
No. Settings vary depending on blank quality, coating, ink, paper, heat press accuracy, pressure and environment. Treat all settings as starting points and test before production.
Why do sublimation colours look dull before pressing?
Sublimation prints often look dull on paper because the final colour develops during heat transfer when the dye bonds with polyester fibres or a polymer coating.
Why does sublimation ghosting happen?
Ghosting is usually caused by paper movement during or after pressing, moisture, incorrect pressure or lifting the transfer while the dye is still active.
Can sublimation work on cotton?
Standard sublimation works best on polyester or polymer-coated surfaces. It does not permanently bond to normal cotton without special coatings or hybrid products.
Why do sublimation blanks turn yellow or brown?
Yellowing or browning is often caused by excessive heat, excessive dwell time, poor coating quality, moisture or using blanks that are not suitable for sublimation.
