Abstract
A dye-donor element is described which contains an area which does not contain any image dye. A receiving element containing thermally transferred image dyes is reheated by a thermal print head with an area of the dye-donor which does not contain any dye located therebetween. Stratification of the transferred image dye in the receiver is thereby reduced.
