In addition to providing uniform heat, the design of the hot press must also accurately control the temperature. When you use transfer, appropriate application temperature is critical to the success of ready-made clothes. If you transfer at too low a temperature, you may not be able to activate the adhesive needed to fix the graphics to the clothes. If too much heat is used to transfer, the adhesive may be squeezed out of the image edge, resulting in unwanted contours or smears. Overheating can also lead to "penetration", which reduces the opacity of graphics.
