Before you buy sublimation gear, nail the essentials: sublimation bonds dye to polyester or poly-coated blanks using heat (±170–200 °C) and firm, even pressure. You’ll need a dedicated ink-tank printer with sublimation ink, a reliable heat press, and design software with correct ICC profiles. Budget for ongoing costs (paper, tape, blanks), routine maintenance (nozzle checks, regular prints), and stable power/ventilation. Know the limits: best on white/light polyester—100% cotton and dark garments need special coatings or other methods. Master the workflow (design → mirror → print → press → cool) for consistent, vibrant results—and consider a short basics course to avoid costly mistakes.
