If sublimating on 3D objects, then a 3D oven press will be needed. Once again, the oven presses can range from smaller “desktop” units to machines the size of a walk-in room. Instead of printing onto transfer paper, the images will be printed onto transfer film, which is able to conform around the edges of the object being decorated. A fixture is needed to hold both the object and printed film in place. A vacuum hose is attached so the printed film thermoforms around the object and, when the oven heats up to 400°F, the Inkjet Sublimation Paper process takes place.
