  • Publication number: 20240059088
    Abstract: The invention relates to a method of printing onto the surface of a substrate, which method comprises a. coating a donor surface with individual particles, b. treating the surface of the substrate to render the affinity of the particles to at least selected regions of the surface of the substrate greater than the affinity of the particles to the donor surface, and c. contacting the surface of the substrate with the donor surface to cause particles to transfer from the donor surface only to the treated selected regions of the surface of the substrate, thereby exposing regions of the donor surface from which particles are transferred to the corresponding regions on the substrate, and wherein that at least 50 wt.
