ABSTRACT:
A method for transferring colorant from a donor element to a dye receiving layer to form a desired label includes providing an embossed surface on the dye receiving layer having desired spacing to minimize mottling; positioning the embossed surface of the dye receiving layer in the focal plane of a focused laser beam with a colorant donor element being positioned in transferable relationship with the dye receiving element; and focusing a laser beam on the colorant donor element to heat the donor element to a sufficient temperature to transfer colorant to the dye receiving element to thereby effect the transfer of colorant from the donor element to the dye receiving layer. The method also includes providing relative movement between the dye receiving layer and the laser beam and modulating the laser beam in correspondence with a data record, thereby effecting laser thermal colorant transfer to the embossed surface on the dye receiving layer from the donor element in correspondence with a desired label so that the embossed spacing provides a high quality mottle free label.
