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 by a thermal print head via the rear side of the transfer member to selected regions of the imaging surface to render particles coating the selected regions tacky, and a transfer station at which the imaging surface of the transfer member and the substrate surface are pressed against each other to cause transfer to the surface of the substrate of the particles that have been rendered tacky.

Transfer member for printing systems

There is disclosed a layered article that can be used in indirect printing, in analog or digital processes. The layered article, when configured as a transfer member, may serve to receive an ink in any form, allow the ink to be treated so as to form an ink image, and permit the application of the ink image on a substrate. The transfer member comprises a support layer and an imaging layer, which may be formed of a silicon matrix including dispersed carbon black particles. Methods for preparing the same are also disclosed.

Thermal transfer printing

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.

Thermal transfer printing

A method and apparatus for thermal transfer printing onto selected regions of a substrate are disclosed. The method comprises: a) providing a transfer member having an imaging surface; b) coating the imaging surface with particles formed of, or coated with, a thermoplastic polymer; c) removing substantially all particles that are not in direct contact with the imaging surface to leave a uniform monolayer particle coating on the imaging surface; d) applying energy to selected regions of the imaging surface to heat and render tacky particles of corresponding regions of the monolayer coating; and e) pressing at least portions of the imaging surface and the substrate surface against one another, either during and/or after application of energy, to cause transfer to the surface of the substrate of the particles of the corresponding regions that have been rendered tacky. The monolayer coating can be replenished with new particles and the cycle repeated.
