Heat Transfer Processing: Hard versus Soft Substrates
Repressing may or may not be needed, depending on the substrate.
There are some differences in heat-transfer applications between hard and soft substrates. For example, fabrics are stretchable in contrast to hard surfaces, so they require more care when peeling backing off the printed garment. On a soft substrate, repressing is often suggested. This entails laying a sheet of parchment paper on top of the finished design and then repressing for 10 seconds. This step helps ensure that the image has been doubly ingrained into the fibers of the garment. Repressing is not necessary when working with hard surface items.
