Moisture can make a mess of your sublimated supplies, so it’s always good to make sure humidity is kept to safe levels. Protect your sublimation paper from humidity by keeping it in a plastic bag, or a resealable bin. If you’re worried the paper you’re using is too moist, set it on your press for a few seconds. The warmth will help remove excess moisture from the paper. The pre-press technique can also work for garments. Also, using a cover that absorbs moisture, like newsprint, in place of Teflon can help eliminate moisture problems. Just make sure to change out the absorbent cover sheet after every press.
