    摘要: An ink jet head comprises a plurality of discharge pressure generating elements serving as the discharge pressure source for discharging an ink droplet, an orifice plate having a plurality of ink discharge ports corresponding to the respective discharge pressure generating elements formed therefor, an ink supply port for supplying ink and a nozzle wall forming an ink flow path communicating the ink discharge ports with the ink supply port. The orifice plate and the nozzle wall are formed by resin material, and also, a thin metallic film is formed on the outer surface of the orifice plate. If desired, a water-repellent film is formed further on the surface of the thin metallic film. With the metallic film formed on the surface of the orifice plate, the moisture in ink is effectively prevented from being evaporated. Further, with the provision of the metallic film, it becomes possible to perform the eutectoid plating for the formation of the water-repellent film. With the head thus structured, it becomes possible to stably obtain excellent print quality.

    摘要: The present invention provides an ink-jet printing head, and an ink-jet printing apparatus and method which enable high-gradation and high-quality images to be printed using dots of different sizes. In an ink-jet printing head according to the present invention, at least one second nozzle has its center arranged on an imaginary line extending in a main-scanning direction of the printing head through the center of a first nozzle. The volume of an ink droplet ejected through the second nozzle is smaller than that of an ink droplet ejected through the first nozzle. Further, the number of second nozzles is larger than that of first nozzles.

    摘要: The present invention provides an ink-jet printing head, and an ink-jet printing apparatus and method which enable not only larger-diameter nozzles but also smaller-diameter nozzles to be sufficiently recovered. In an ink-jet printing head according to the present invention, the number of smaller-diameter nozzles is larger than that of larger-diameter nozzles. Further, a plurality of ink channels include first ink channels in communication with the larger-diameter nozzles and second ink channels in communication with the smaller-diameter nozzles. The first ink channels and the second ink channels are mixed and arranged along an ink supply port so that a group of smaller-diameter nozzles composed of a plurality of the smaller-diameter nozzles is arranged between the lager-diameter nozzles.
