Definitions

  • the donor element comprises a heat transferable dye, sometimes called a thermal transfer dye, usually in a formulation with a binder, supported on a substrate.
  • the dye donor element is contacted with a receptor sheet, and the surface of the substrate irradiated with an infra-red laser to transfer the dye to the receptor sheet.
  • a dye which strongly absorbs the wavelength of the exciting laser is required for the heat transferable dye to be directly heated by the laser. This need to match the infra-red absorption of the dye to the emission of the laser greatly restricts the number of dyes which can be used in the laser-induced thermal transfer process.
