Abstract
Printing methods and apparatus for thermal transferring dye from a dye donor to a dye receiver wherein electromagnetic radiation such as a laser beam is applied through the dye receiver to effect dye transfer. Either or both of the dye donor and the dye receiver used with such printing methods and apparatus can be in the form of individual sheets or continuous ribbons and may be either stationary or moving. In various embodiments, the dye receiver is held between a convex surface of a rigid support plate and the dye donor during thermal transfer of dye. A variety of methods and devices for providing electromagnetic radiation and for transporting dye donors and dye receivers during printing are also disclosed.
