20130328954 | PRINTING APPARATUS AND PRINTING METHOD - A printing apparatus includes a head having a nozzle through which ink that contains thermoplastic resin particles and whose viscosity at 50° C. is equal to or greater than 2.1 mPa·s is discharged, a pressure chamber, and a driving element; an ink non-absorptive medium; a heating unit; and a control unit that applies driving signals to the driving element. In the printing apparatus, a discharge waveform generated by the driving signal includes a first expansion-element that expands the pressure chamber, a contraction-element that contracts the pressure chamber having been expanded by the first expansion-element, a second expansion-element that expands the pressure chamber having been contracted by the contraction-element, a third expansion-element that further expands the pressure chamber having been expanded by the second-expansion element, and a connection-element that connects an end terminal of the second expansion-element with a start terminal of the third expansion-element at the same potential. | 12-12-2013 |
20140085365 | PRINTING APPARATUS AND PRINTING METHOD - A printing apparatus, has a head having a plurality of nozzles for discharging an ink containing thermoplastic resin particles and having a viscosity at 50° C. of 2.1 mPa·s or more to a non-ink-absorbing medium and a drive element provided in each of the nozzles, a heating portion which heats the medium, and a control portion which drives the drive elements by applying a drive waveform to discharge ink droplets from the nozzles corresponding to the drive elements, in which a first ink droplet is discharged from the nozzle by the application of the drive waveform to the drive element, and the discharge speed of an ink droplet whose discharge speed is lower of a second ink droplet and a third ink droplet discharged accompanying the first ink droplet is 4.0 m/s or more. | 03-27-2014 |
20140152741 | INK JET RECORDING APPARATUS - An ink jet recording apparatus includes a recording head having a plurality of nozzles through which an ink composition containing an inorganic pigment is ejected, a nozzle surface having nozzle orifices, and a liquid-repellent film disposed on the nozzle surface; an absorbing member that absorbs the ink composition containing the inorganic pigment from the nozzle orifices and the nozzle surface; and an actuating mechanism including a pressing member that presses the absorbing member, which contains an impregnation liquid, and the nozzle surface relative to each other. The actuating mechanism moves at least one of the absorbing member and the recording head relative to the other to perform a cleaning operation in which the ink composition is removed from the nozzle surface with the absorbing member. | 06-05-2014 |
20140152742 | INK JET RECORDING APPARATUS - An ink jet recording apparatus includes a recording head having a plurality of nozzles through which an ink composition containing an inorganic pigment is ejected, a nozzle surface having nozzle orifices, and a liquid-repellent film disposed on the nozzle surface; an absorbing member that absorbs the ink composition containing the inorganic pigment from the nozzle orifices and the nozzle surface; and an actuating mechanism including a pressing member that presses the absorbing member and the nozzle surface relative to each other. The actuating mechanism moves at least one of the absorbing member and the recording head relative to the other to perform a cleaning operation in which the ink composition is removed from the nozzle surface with the absorbing member. The absorbing member contains an impregnation liquid having a surface tension of 45 mN/m or less during the cleaning operation. | 06-05-2014 |
20140232782 | INK COMPOSITION AND INK JET RECORDING METHOD - An ink composition contains a pigment, first wax particles, second wax particles, and a resin emulsion, in which the first wax particles have a melting point of 120° C. or higher and 170° C. or lower, the second wax particles have a melting point of 70° C. or higher and less than 120° C., the resin emulsion has a glass transition point of 50° C. or higher and 150° C. or lower, the first wax particles contain one or more kinds of wax particles selected from the group consisting of polyethylene wax particles or polypropylene wax particles, and the second wax particles contain one or more kinds of wax particles selected from the group consisting of polyethylene wax particles. | 08-21-2014 |
20140240393 | INK SET FOR INK JET RECORDING, AND RECORDING APPARATUS - An ink set includes a recording ink and a displacement ink. The recording ink contains a pigment, a resin, water, and a first surfactant and is substantially free of alkyl polyols with a normal boiling point of 280° C. or more. The displacement ink contains water, a second surfactant, an aprotic polar solvent, and an alkyl polyol with a normal boiling point of 280° C. or more. Each of the first surfactant and the second surfactant includes a silicone surfactant and/or a fluorosurfactant. The resin includes a water-soluble resin and/or a resin emulsion. The recording ink has a higher surface tension than that of the displacement ink. | 08-28-2014 |
