The process of laser transfer printing is actually composed of the following parts: color toner fusing (hot-melt adhesive pigments are formed on the hot-melt adhesive coatings of the transfer paper by photoelectric principle and solidified at high temperatures); hot-melt coating pattern transfer (hot-melt adhesive coatings are melted by high temperature and pressure and transferred to the substrate surface) The combination of base paper stripping (image separation technology). Because the complex printing process is concentrated on the special coating of laser transfer paper, The presence of laser transfer paper makes color transfer printing easier and more convenient.
