    摘要： A thermal transfer sheet including: a first substrate; and a first transfer layer and a peel-off layer provided on one surface of the first substrate in a frame sequential manner, wherein the first transfer layer after transfer under the following condition (A) has an arithmetic mean height Sa of more than 0.1 μm and less than 0.6 μm, and the peel-off layer has an arithmetic mean height Sa of more than 0.1 μm and less than 1.0 μm,



    [Condition (A)]
    an intermediate transfer medium including a receiving layer having a surface with an arithmetic mean height Sa of 0.1 μm is prepared, and the first transfer layer of the thermal transfer sheet is placed opposite the receiving layer of the intermediate transfer medium, and an application energy of 0.167 mJ/dot is applied to transfer the first transfer layer of the thermal transfer sheet to a surface of the receiving layer of the intermediate transfer medium.

    摘要： A printing assembly is disclosed for thermal transfer printing onto a surface of a substrate. The assembly comprises at least one first printing system comprising 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 thermoplastic particles is applied to the imaging surface, an imaging station at which energy is applied by a thermal print head, optionally via the rear side of the transfer member, to selected regions of the imaging surface to render particles coating the selected regions tacky, a transfer station at which the imaging surface of the transfer member and the substrate surface are pressed against each other to transfer to the substrate the particles that have been rendered tacky to form an adhesive image; and at least one more printing system downstream from the first system.
