The company may say that there are "no profiles" but that just means you get general colors that will still need to be tweaked. With sublimation there are too many variables for them to say that you won't need an ICC profile. It really depends on your setup and what blanks that you're using. Like NoXid, I use InkOwl as they have a good color gamut and their inks are available individually at different sizes. They also provide some ICC profiles but I ended up building my own for each substrate.
