    Abstract: 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.

    Abstract: 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.

    Abstract: For a dither matrix used when converting multivalued data into image data for an output apparatus, thresholds are set such that: a first dot and a second dot alternately become larger until both of the first dot and the second dot reach a first dot size; after both of the first dot and the second dot reach the first dot size, the first dot becomes larger until the first dot reaches a second dot size while the second dot does not become larger, and thereafter, the second dot becomes larger until the second dot reaches the second dot size while the first dot does not become larger; and after both of the first dot and the second dot reach the second dot size, the first dot and the second dot alternately become larger.

    Abstract: An image forming apparatus including a photoconductor and a light emitting unit. The image forming apparatus including: a generating unit configured to generate correction data used for correcting a shift in the sub-scanning direction of the latent image to be formed on the photoconductor; a correcting unit configured to correct image data based on the correction data; and a control unit configured to control light emission of the light emitting unit so as to form the latent image on the photoconductor. The generating unit is configured to generate the correction data based on configuration information of the light emitting unit, information indicating time required for causing the plurality of light emitting elements to emit light, and information indicating a rotation speed of the photoconductor.
