Why does DTF powder stick around the printed design?

More detailed information:

If the film contains moisture, it can mix with the ink, slowing its drying. Powder applied to these wet areas will stick more, creating an uneven cured surface and making peeling difficult, some parts may even lift off.

Excess moisture can also form small bubbles under the powder (see Figure 1).

Over a few days, this moisture escapes as water, giving the print or film a “sweating” appearance.

Troubleshooting Tips

• Moisture on the film: The first 1–2 metres of exposed PET film may be affected by humidity. Trim the first metre or two before printing.

• Excess powder: Gently tap the back of the film or use a soft brush to remove powder outside the print area.

• Moist powder: If the powder is too damp, use a fresh bag. Store the moist powder in a sealed container with silica pouches for a few days to dry it.
