The sublimation ink is first printed in reverse on a carrier paper and then transferred onto the fabric. Through pressure and temperature, the dye 'sublimates' from the paper into the fibre of the fabric. For this a thermal transfer press is used and transfer paper & fabric are compressed together for approx. 60-90 seconds at up to 220°C. The dye is then sublimated onto the fabric. This results in excellent colour brilliance and contour sharpness. Transfer printing is relatively inexpensive and can be applied to almost any synthetic fibre, mostly polyester. But even very highly elastic fabrics can be printed without any problems.
