DTF hot melt powder is a TPU adhesive dusted onto wet printed film before curing. Heat-pressed, it bonds the design permanently to fabric — without it the print will not adhere or survive washing. Imprint Solution stocks white and black powder in multiple micron grades.

Fine powder (below ~80 micron) gives a soft hand feel and fine detail, best for light fabrics. Medium and coarse grades give stronger adhesion on thick or textured fabric. Most garment shops use fine-to-medium white; coarse suits heavy workwear and stretch durability.

White powder suits light-coloured transfers and is the general-purpose choice. Black powder sits under dark designs so any residue at the print edge stays invisible. Function is otherwise identical — both are TPU hot melt adhesives graded by micron size.

A single A4 transfer uses roughly 3–5 grams of powder and an A3 around 6–10 grams, depending on ink coverage. A 1kg pack covers several hundred A4 prints. Powder is one of the lowest per-print costs in DTF, well behind ink and film.
