Why do DTF prints become oily / greasy after sitting?

DTF white ink has an chemical called glycerin to prevent the heads clogging. It can absorb moisture from the air as it sits in storage. Because of its physical properties, glycerin cannot be dried. If the drying process is insufficient, glycerin will appear on the DTF transfer film after a period of time and it will create oily spots on your print .

It is recommended to cure your DTF prints for 125c at 3-4 minutes.

During the powder curing period you will need to exhaust all gases and oils out and away from the oven.
