Method and system for thermal transfer printing are disclosed. The system includes a transfer member having 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 electromagnetic radiation (EM) 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 only the regions of the particles coating that have been rendered tacky are transferred to a substrate. The transfer member includes on its rear side a body transparent to EM radiation and on its front side an EM radiation absorbing layer, the imaging surface being formed on, or as part of, the absorbing layer.
