摘要： In a dye transfer printer, a donor web having successive dye transfer areas that are used for printing and opposite longitudinal edge areas alongside each one of the dye transfer areas that are not used for printing are wrapped under longitudinal tension about a cylindrical spool core. The dye transfer areas that are wrapped under tension about the spool core are stretched thinner than the two edge areas that are wrapped under tension about the spool core due to their being heated during printing. The spool core is depressible inward at respective portions on which the two edge areas are wrapped under tension and is not depressible at an intermediate portion between the depressible portions on which the thinner transfer areas are wrapped under tension. As a result, a convolution build-up of the edge areas on the spool core will be no more than a convolution build-up of the thinner transfer areas on the spool core. This substantially reduces the likelihood of any creases being created in the dye transfer areas which would cause line artifacts to be printed on a dye receiver.
