Abstract
A method of and an apparatus for making thermocopies in which a receiving material and an ink carrier member are synchronously advanced into a sublimation area opposite each other in a predetermined relationship therebetween, and the ink carrier member is heated linewise by a modulated laser beam to provide for pixelwise heating of the ink carrier member to enable transfer of an ink layer of a predetermined density from the ink carrier ribbon to the receiving material.
