摘要： Systems and methods for laser assisted deposition of a material includes a printing unit configured to print individual dot-like portions of a material from a donor substrate onto a receiving substrate, and a vacuum shuttle configured to be positionable in two or three dimensions between the printing unit and the donor substrate and to engage the donor substrate upon application of a vacuum to the vacuum shuttle. The printing unit may include a coating system and a laser. The vacuum shuttle includes a vacuum channel about its periphery and an open window through which the laser irradiates the donor substrate. The vacuum channel is fluidly coupled to a vacuum inlet for receiving a vacuum suction, thereby to engage the donor substrate and hold it taught against the bottom of the vacuum shuttle in operation. The vacuum shuttle may also include one or more distance measuring sensors and fiducial markers.

摘要： Fountain solution latent images are provided on an inking blanket without using laser-induced evaporation systems. Approaches include a rotatable charge retentive surface configured to receive an unfused toned electrostatic pattern of toner particles adhered thereto via electrophotography. The toner includes small diameter polymeric or inorganic particles that may have no color pigment to appear transparent or translucent. Fountain solution is disposed on at least one of the toner, the charge retentive surface and a transfer substrate. The transfer substrate is adjacent the charge retentive surface and forms a nip therebetween, with the transfer substrate sandwiching the unfused toned electrostatic pattern of toner particles and fountain solution against the charge retentive surface at the nip. Fountain solution sandwiched between the surfaces splits as the surfaces separate downstream the nip, leaving a fountain solution latent image remaining on the transfer member surface based on the electrostatic charged pattern on the charge retentive surface.

摘要： A thermal printhead includes a substrate, a resistor layer with heat generation portions supported by the substrate and aligned in a primary scanning direction, a wiring layer supported by the substrate to form a conductive path to the heat generation portions, an insulating layer interposed between the substrate and the resistor layer, and a reflection layer located opposite to the heat generation portions with respect to the insulating layer. The reflection layer overlaps with the heat generation portions as viewed in a thickness direction of the heat generation portions and has a greater heat reflectivity than the insulating layer.

摘要： A thermal head includes: a substrate; a thermal storage layer disposed on the substrate and having a ridge portion; heat generating portions disposed on the ridge portion; and electrodes which are disposed on the substrate. At least one of the electrodes has a first corner portion at which a side surface and an upper surface intersect, more upstream in the conveyance direction of the recording medium than the top portion of the ridge portion. In a cross section of the thermal head, an inclination angle of an imaginary line which connects an intersection point of an imaginary line which hangs downward from the top portion (13b1) of the ridge portion and the substrate, with the first corner portion, is 75° or less from the substrate. Thus, printing residue is less likely to adhere to the thermal head.

摘要： A thermal printer having a thermal printhead with energy save features which is capable of high speed and high quality printing is provided. The thermal printer has an energy storage device and a thermal printhead including a substrate, a resistor layer formed on one surface of the substrate, and a thermoelectric element disposed on the other surface of the substrate opposite to where the resistor layer is formed, wherein the thermoelectric element converts heat generated by the resistor layer to electrical energy when a temperature difference between the resistor layer and an opposite side of the thermoelectric element where the resistor layer is disposed nearby becomes large enough for the thermoelectric element to convert heat into electric energy, and the electrical energy is stored in the energy storage device.
