Thermal transfer ribbons are coated with wax, resin, or a hybrid formulation to match application needs and substrate type. Wax is economical and suited for paper labels; Wax‑Resin offers moderate durability on synthetic surfaces; full‑Resin is ideal for harsh environments with resistance to chemicals, abrasion, and heat. Choosing the right ribbon ensures high‑quality, long-lasting prints and minimizes wear on the printhead.
