The design is printed on to the transfer paper using sublimation inks. By using special transfer machinery the design is transfered onto the cloth. This is a successful technique for sporting clothing, women's fashion, soft-signage and promotions. However every transfer paper and ink has its own characteristics as well as the machinery. The results need to be optimized. The paper drying capacity, the take up into the layer on the paper, the amount of ink which needs to be used are critical features.
This will depend on clear information about your production requirements: the optimal combination of printing speed, sublimation ink and transfer paper is essential to the optimal printing result. I can give recommendations for tried and tested solutions instead of having to resort back to a time-consuming trial and error process.
