ABSTRACT:
A process and apparatus in which a thermal dye is not carried by a donor element or sheet, but is provided in liquid form to a reservoir which supplies the dye to the surface of a donor roller. The dye is transferred to a transparent receiver sheet which is in close proximity to the roller surface, by exposure of the dye to an information-bearing radiation beam which is projected through the receiver member. Such a process and apparatus eliminates the need for a separate dye-donor element, and results in a lower cost process.
