Can I print on any kind of garment with sublimation?

Not directly. The sublimation process only works on a white surface, and it needs to be polyester. This can be a polyester coating. However you can sublimate on a polyester intermediate carrier like subli-flex or subli flock. After printing these intermediate carriers can be cut by hand or a Print & Cut system and then be transferred onto most types of colored garments like cotton, mixes, and many others.
