The process of applying a printed image directly on the garment in order to transfer it to the garment itself is known as a heat transfer. This technology has typically been used to personalise t-shirts and, more recently, to apply "tag-less" labels. The pattern will endure the lifespan of the garment since the heat transfer method ensures that it is ingrained into the sublayers of the printed surface. https://www.orianaa.com/products/heat-transfer-labels
