This is where printed film becomes part of your garment. Start with one test application and keep the settings that work. Supplied transfer instructions take priority; fabric, film and press setup matter.
Prepare the garment, position the printed film, peel after pressing, then cover for the finishing press. Follow the supplied transfer instructions if they differ from the settings below.
Use a heat press with reliable temperature, time, and pressure controls. Have a lint roller, heat-resistant cover sheet, and a flat heat-safe work area. A household iron does not provide consistent pressure for this process.
Check the garment care label and heat tolerance. Remove lint and moisture. Pre-press for 3–5 seconds, then smooth the garment and keep seams, buttons, and zippers outside the pressing area.
For a heat-compatible cotton garment, start at 310°F / 155°C for 7-10 seconds with medium-firm, even pressure. Position the transfer with the printed artwork facing up and adhesive against the fabric. Close the press for the full time.
Let the film cool briefly until warm, then peel smoothly and close to the fabric. Cover the applied print with a heat-resistant finishing sheet and press again for 2-3 seconds at the same temperature. Let the garment cool flat.
Instructions supplied with a particular transfer batch take priority because film and adhesive requirements can change. Record the settings that work on your press and garment.
Hot, warm, and cold peel
Hot peel means removing film immediately after the press opens. Warm peel means waiting briefly for the film to lose its initial heat. Cold peel means waiting until the transfer reaches room temperature. DTF One’s standard instructions use warm peel.
Do not guess from another supplier’s film. If artwork lifts with the carrier, stop peeling, lay the film back down, check the supplied instructions, and repress before trying again.
Fabric cautions and dye migration
Cotton and suitable cotton/poly blends are common starting points. Polyester, dyed performance fabrics, water-resistant coatings, nylon, and heat-sensitive materials need a test before a full order. Do not assume every fabric accepts the same recipe.
Dye migration can tint light artwork after heat is applied to dark polyester. Lower heat alone does not guarantee prevention. Test the actual blank, inspect after cooling, and watch for delayed color change. Avoid seams that prevent even pressure.
Washing and drying
Wait 24 hours before the first wash. Wash inside out in cool water with mild detergent. Avoid bleach and fabric softener. Air dry for gentle care; avoid high dryer heat. Do not dry clean or iron directly over the print.
Keep a care note with finished garments so the person wearing them knows how to protect the print.
Lifting or incomplete release
Pause the affected run. Check the supplied instructions, platen temperature, pressure, moisture, seams and peel timing. If part of the design stays on the carrier, return it carefully to position and follow the supplied pressing instructions. Do not stretch a hot print.
Scorching or press marks can involve heat, time, pressure or a sensitive fabric. Stop and review the garment care limits and supplied transfer instructions before testing again.
For an unwanted background or lost detail, compare the received transfer with your submitted file. A background present in the file will print; pressing cannot remove it. Check transparency and fine detail at final size. If the transfer differs from the file, or the cause is unclear, keep both and ask for an issue review.
