    摘要： A liquid discharge head includes a nozzle plate having multiple nozzles from which a liquid is dischargeable in a discharge direction, the multiple nozzles arrayed in a nozzle array direction; an individual channel member including individual channels respectively communicating with the multiple nozzles; multiple pressure generators to generate pressure to discharge the liquid from the multiple nozzles, respectively; a wiring member including a drive circuit; a protector adjacent to at least one side of the nozzle plate in a direction perpendicular to the discharge direction and overlapping the drive circuit of the wiring member in the discharge direction; a housing holding the protector, the nozzle plate, and the individual channel member; and a gas channel. The housing has a gas inlet; and a gas outlet. The gas channel is between the protector and the wiring member and communicates with each of the gas inlet and the gas outlet.

    摘要： A liquid discharge apparatus includes a conveyance path, a conveyor, and a liquid discharger. The conveyor conveys a medium in a conveyance direction along the conveyance path. The liquid discharger is disposed above the conveyance path to discharge a liquid toward the medium conveyed by the conveyor. The liquid discharger includes a discharge head, a housing, an airflow generator, and slit. The discharge head has a nozzle from which the liquid is discharged. The housing accommodates the discharge head. The housing has a lower face from which the nozzle of the discharge head is exposed and a slit adjacent to the discharge head in the lower face of the housing. The airflow generator generates an airflow flowing through the housing and discharged from the slit toward the conveyance path.

    摘要： The effect of air resistance acting on ink drops discharged from nozzles of an ink-jet head is appropriately controlled, for example, by means of a method suitable for a breathable medium, such as a cloth and the like. In this way, for example, high-resolution printing, printing with a great gap distance, and the like is properly implemented.An ink-jet printer 10, for printing on a breathable medium 50 through which air passes from a printing surface to a rear surface, includes an ink-jet head 12 for discharging ink drops toward the medium 50, and a rear side component 14, having a hollow portion that opens its space toward the rear surface of the medium 50; and then ink-jet head 12 includes nozzles for discharging ink drops to the medium 50, and an airflow blowing section for blowing airflow, at least a part of the airflow going through a travel path of the ink drops, and the airflow moving toward the medium 50 together with the ink drops; and the rear side component 14 receives the airflow, passing through from the printing surface of the medium 50 to the rear surface of the same, with the hollow portion.

    摘要： The present subject matter relates to a method and system for pulsed air-actuated micro-droplet on demand jetting, especially for jetting high viscosity liquids. A needle extends from a liquid chamber and terminates in a drop-forming orifice outlet from which micro-droplets are generated. At least two air jets direct a timed pulse of air at the drop-forming orifice outlet of the needle. The pulsed air is synchronized with the formation of a desired volume of liquid at the orifice outlet to extract and propel a micro-droplet at high velocity to a substrate. The air jets are turned on prior to the forming of the desired volume at the orifice outlet of the needle, and turned off after the micro-droplet had been produced.

    摘要： To suitably use a metallic ink or a pearl-colored ink in an inkjet printer. Furthermore, to suitably use an ink containing a large-sized pigment in the inkjet printer.An inkjet printer includes an inkjet head 12 that discharges towards a printing medium 50 ink droplets of a metallic ink or a pearl-colored ink. The inkjet head 12 includes a nozzle 104 that discharges the ink droplets towards the printing medium 50, and an air blowing unit 120 that generates an airflow towards the printing medium 50 along the ink droplets discharged from the nozzle 104.
