Outgassing
The release of gases from garment dye or fabric treatments during heat pressing. Outgassing can cause bubbling, discoloration, or poor adhesion of DTF transfers, particularly on polyester. Pre-pressing the garment for 3-5 seconds before applying the transfer helps release trapped gases.

A phenomenon where sublimation dyes in polyester fabrics bleed through the DTF transfer during heat pressing, causing discoloration or color shifting. Common with red, bright blue, and black polyester. Prevented using dye-blocking sprays, lower temperatures, or specialty films.
A machine that applies heat and even pressure to transfer DTF prints from film onto garments. Standard DTF pressing temperatures range from 300-330°F (149-165°C) at medium-firm pressure for 10-15 seconds. Available in clamshell, swing-away, and drawer styles.
