How are blank sublimation iron-on patches applied?
Blank sublimation iron-on patches are applied by first printing your desired design onto the sublimation surface using sublimation ink and transfer paper. After transferring the design with a heat press, allow the patch to cool before positioning it on the garment. Place the patch on clean, dry fabric and use a heat press at the recommended temperature, pressure, and time for the patch material. Once securely bonded, let it cool completely before wearing or washing the item.
