Abstract
This invention relates to a method for transferring a protective overcoat for a thermal print wherein the protective overcoat is applied to a dye-donor element under predesigned conditions after thermal dye transfer, the dye-donor element comprising patches of dye for transfer to a thermal print to provide a protective layer thereon. In particular, the invention improves the process of providing an improved level of gloss to the transferred protective overcoat. The method involves a preselected duration between printing and peeling the transferable laminate patch, respectively, to and from the donor. The invention is particularly advantageous at lower line times, faster printing, for thermal prints with high gloss.
