Choose washing in low temperatures, about 30-40 oC (86-104 F) or even at a cold wash and use medium washing cycles (600-800 rpm). In addition, washing programs of smaller times.
After washing the fabrics, air dry them. The use of a tumble dryer is not suggested, as the high temperatures can have an impact on the print. Keep the t-shirts turned inside out (the print’s side on the inside) when they are exposed to the sun. Sunlight affects the vibrancy of the print and causes fading of the color due to photo degradation.
