Heat Transfer Settings & Equipment

Most heat presses have 10-20°F calibration offset between display and platen. Use a laser thermometer on the actual platen to get true temperature. Adjust your working temperature accordingly. If difference is >20°F, the press may need professional recalibration.

No. White/light fabrics tolerate 330-350°F; dark fabrics should use 300-320°F to avoid scorching. Poly-blends need lower temps than 100% cotton. Ceramics/mugs require 350-400°F for sublimation. Always test on the actual substrate type before full production.

Proper pressure varies by transfer type: HTV typically 4-6 PSI, sublimation typically 2-4 PSI, UV DTF typically 4-6 PSI. Too much pressure: stretches fabric or crushes detail. Too little: transfer won't adhere. Use a pressure gauge to measure actual PSI and adjust.

Causes: temperature too low, insufficient press time, inadequate pressure, or wet/damp substrate. Increase temperature by 5-10°F, extend time by 2-3 seconds, or verify pressure is within spec. Check substrate is dry before transfer.

Scorching indicates temperature too high or time too long. Reduce temperature by 5-10°F and/or reduce time by 2-3 seconds. Test on scrap substrate. If still scorching, check if press is over-heating (may need maintenance).

Monthly for high-volume shops (1000+ transfers/week), quarterly for medium-volume (100-500/week), semi-annually for low-volume. Equipment drift is cumulative. Regular validation prevents quality degradation.
