Thermo film is a good solution on sports clothes. Numbers and logos are cut out of thermo film by film cutter and are pressed on the surface of jerseys and shorts. The film retains the colours very well and does not let them fade.
The printed heat pressure film is applied on white film, which is then printed on the surface of the textile item. The entire spectrum of colours can be applied. In case the heat pressure film is applied, colours may start fading after washing the items 15-20 times.
Recommendation: when washing the printed clothing items turn the inside out and wash in water with the temperature below 40˚C.
