Title: THERMAL CONDUCTION TRANSFER PRINTING
Abstract:
A printing system is disclosed for thermal transfer printing onto a surface of a substrate. The system comprises a transfer member having opposite front and rear sides with an imaging surface on the front side, a coating station at which a monolayer of particles made of, or coated with, a thermoplastic polymer is applied to the imaging surface, an imaging station at which energy is applied via the rear side of the transfer member to selected regions of the particles coated imaging surface to render the particles thereon tacky within the selected regions, and a transfer station at which said imaging surface of said transfer member and the substrate surface are pressed against each other to cause transfer to the surface of the substrate of only the regions of the particle coating that have been rendered tacky. In the invention, the imaging station comprises a thermal print head in thermal contact with the rear side of the transfer member and operative to apply energy to the particles on the imaging surface by heat conduction through the transfer member.
