THERMAL TRANSFER PRINTING

WIPO Patent Application WO/2018/100528

A3

A method and system are disclosed for thermal transfer printing onto selected regions of 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 in the form of electromagnetic (EM) radiation 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 the imaging surface and the surface of the substrate are pressed against one another 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 rear side of the transfer member is formed of a body transparent to the EM radiation, and an EM radiation absorbing layer made of an elastomeric silicone is provided on the front side of the transfer member adjoining the transparent body, the imaging surface being formed on, or as part of, the radiation absorbing layer.
