Heat Press Settings Chart for DTF Transfers
Below is a highly summarized Standard Operating Procedure (SOP) Reference Table. It consolidates the core DTF heat press parameters for the four major fabric categories into a single sheet for quick production decision-making.
⚠️ Note: These ranges are based on standard DTF PET Film + Hot Melt Powder and cover 90% of commercial heat press scenarios. Parameters represent the Primary Press only (Second Press not included).
DTF Pressing Parameters by Fabric Type
| Fabric Category | Temp Range (°C) | Time Range (sec) | Pressure Range | Core Control Logic | Detailed Settings |
|---|---|---|---|---|---|
| 100% Cotton | 145–165°C | 10–15 s | Medium → High | Thicker fabric = Higher pressure | View Cotton Table |
| 100% Polyester | 130–150°C | 8–15 s | Medium → Mid-High | Temp control to prevent sublimation | View Polyester Table |
| Poly-Cotton Blends | 145–155°C | 10–15 s | Medium → Mid-High | Balance between Cotton & Poly | View Blends Table |
| Canvas | 145–160°C | 12–15 s | Mid-High → High | Pressure first, temperature second | View Canvas Table |
Pressure Level Definitions
| Pressure Level | Physical Feel | Typical Applications |
|---|---|---|
| Medium | Noticeable resistance when closing | T-shirts, thin blends |
| Mid-High | Requires clear effort to lock down | Sweatshirts, standard blends, polyester |
| High | Requires significant force to press down | Canvas, heavyweight fleece |
Quick Memory Mnemonic
Cotton depends on thickness, Polyester needs temperature control, Blends take the middle ground, and Canvas must be pressed hard.
Production Notes
- Temp is NOT "Higher is Better": Overheating Polyester or Blends leads to fabric glossing, dye sublimation, or migration.
- Insufficient Pressure is the #1 Failure Cause: This is especially true for thick cotton and canvas.
- Second Pressing is Worth It: While not mandatory, 140–150°C × 5–8 seconds significantly improves washability and hand-feel.
Summary
DTF parameters are not about finding a "magic number." Instead, they are about working within the fabric's safety zone while trading Time and Pressure for Adhesion Strength.
