Abstract: A method for enabling D2T2 printing onto non-D2T2 printable substrates uses a diffusible primer material provided on a dye-sheet or ribbon. The primer comprises a polymer, a release agent and a plasticizer. The release agent and the plasticizer are diffused into the substrate, while the polymer remains on the dye-sheet or ribbon. Printing of the primer onto the PC substrate is controlled via a computer image program corresponding to a colored image. This computer image program also controls the printing of the colored image at the primed locations. Accordingly, image-wise treatment of a plastic material via the primer selectively renders the PC substrate surface D2T2 printable at the point of personalization, providing for a 100% PC full card body having the colored image.
