Patent number: 11642905Abstract: 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.Type: GrantFiled: July 27, 2021Date of Patent: May 9, 2023Assignee: Landa Labs (2012) LTD.Inventors: Benzion Landa, Sagi Abramovich, Amit Haviv, Ofer Aknin, Yaakov Valdman, Michael Nagler

Publication number: 20220169059Abstract: A printing assembly for thermal transfer printing is disclosed. The assembly comprises at least one first printing system comprising a transfer member having an imaging surface on the front side, a coating station at which a monolayer of thermoplastic particles is applied to the imaging surface, an imaging station at which electromagnetic radiation (EM) is applied, optionally via the rear side of the transfer member, to selected regions of the imaging surface to render the particles coating the selected regions tacky, a transfer station at which only the regions of the particles coating that have been rendered tacky are transferred to a substrate to form an adhesive image; and at least one more downstream printing system. The transfer member includes on its front side an EM radiation absorbing layer, the imaging surface being formed on, or as part of, the absorbing layer, and on its rear side a body which can optionally be transparent to EM radiation.Type: ApplicationFiled: February 16, 2022Publication date: June 2, 2022Inventors: Benzion LANDA, Sagi ABRAMOVICH, Amit HAVIV, Ofer AKNIN, Yaakov VALDMAN, Michael NAGLER

Patent number: 10913835Abstract: 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.Type: GrantFiled: November 30, 2016Date of Patent: February 9, 2021Assignee: LANDA LABS (2012) LTD.Inventors: Benzion Landa, Sagi Abramovich, Amit Haviv, Ofer Aknin, Yaakov Valdman, Michael Nagler
