Abstract
A thermal printer has converging paths for dye-donor web and receiver medium. The paths abut before proceeding past the thermal head. A transport system moves the dye-donor web and the receiver medium (i) in a forward direction along their respective paths past a thermal head, whereat heat from the thermal head causes an area of the laminate material coating between leading and trailing edges to transfer from the dye-donor web to the receiver medium and (ii) in a reverse direction along their respective paths such that the area of the laminate material which is transferred to the receiver medium breaks cleanly at said trailing edge from a non-laminated area of the laminate material that remains on the aye-donor web as the web support separates from the receiver medium.
