Heat transfer is the process of transferring an image onto a fabric. It has 2 transfer methods; vinyl and digital. Vinyl uses a machine and is best suited for printing sportswear jerseys, slogans or small, multi-colored graphics (or Flock, PU, Glitter, Glow in the dark, reflective and hologram). Digital works like a home printer, using a special solvent ink and is suited for complexed designs.
