An object of the present invention is to provide an inkjet recording device capable of adjusting a clearance between prints formed by two nozzles (114, 115), and capable of printing a print content at a high speed. In order to achieve the object, there is provided an inkjet recording device which has two sub-print heads including nozzles (114, 115), charging electrodes (116, 117), deflection electrodes (118, 119), and gutters (120, 121), in which the two nozzles are disposed in a deflection direction of ink particles, and which performs printing on a printed object (124) while moving the printed object (124) relative to the ink particles in a direction substantially perpendicular to the deflection direction of the ink particles, the inkjet recording device having a function for reducing a clearance between print results (125, 126), printed by the two nozzles (114, 115), by controlling a voltage applied to the charging electrodes (116, 117) and a voltage applied to the deflection electrode (118, 119).

The invention describes a number of methods and apparatus for shortening the inter-message gap on a continuous inkjet printer. Included is a novel phase testing methodology.

The present invention relates to an inkjet print head device for continuous inkjet printing, comprising a transducer; a charge electrode; a deflection plate; a gutter; and a holster; provided that the holster is receiving at least the aforementioned components, wherein the holster comprises an opening for a dedicated outlet for the ink in a printing mode, and wherein the holster further comprises an ink leakage detection area. Further the invention relates to a method and a system for detecting ink leakage in a print head.

In order to suppress adherence of ink splash to an electrode and ink contamination of surrounding environment, in a printing system, there is provided a continuous type ink jet printer having a nozzle for jetting ink in the form of particles, a charging electrode for electrically charging the jetted ink particles, and a deflection electrode for deflecting the charged ink particles. The system includes a printing section for printing an object to be printed with the ink particles jetted from the nozzle and a charging section configured to charge at least one of the printing object prior to its printing by the printing section and surrounding atmosphere in which the printing on the printing object is to be effected by the printing section with a polarity opposite to a polarity of the charge provided to the ink particles by the charging electrode.

An ink jet recording apparatus includes an ink container in which ink to be used to perform printing on a print target is stored, a nozzle which is connected to the ink container and from which pressurized and supplied ink is jetted, charging electrodes that charge ink particles jetted from the nozzle with electricity, deflecting electrodes that polarize the ink particles charged with electricity by the charging electrodes, a gutter that recovers ink not used for printing, a solvent container in which a solvent is stored, and a liquid nozzle which is connected to the solvent container and from which a pressurized and supplied solvent is jetted. The liquid nozzle includes a liquid flow passage portion that extends from the nozzle in a direction of the gutter, and a liquid jet hole that is formed at an angle allowing the pressurized and supplied solvent to hit the nozzle through the liquid flow passage portion.

A continuous inkjet printer includes a linear printhead having a cross-track printhead width that is wider than a cross-track image width. The linear printhead is characterized to determine an image quality level as a function of cross-track position. A segment of the linear printhead is designated wherein the image quality level within the designated segment of the linear printhead is acceptable. A translation mechanism is used to translate the linear printhead relative to the receiver medium such that the designated segment of the linear printhead is aligned with a region on the receiver medium where the image content is to be printed, and the image content is printed on the receiver medium using the designated segment of the linear printhead.

Image content is printed on a receiver medium using a continuous inkjet printer with a linear printhead. A plurality of segments of the linear printhead are designated at different cross-track positions. The linear printhead is translated relative to a receiver medium such that an initial segment of the linear printhead is aligned with a printing region on the receiver medium and the image content is printed using the initial segment of the linear printhead. When an image quality level of the printed image content is determined to fall below an acceptable level, the linear printhead is translated relative to the receiver medium such that a next segment of the linear printhead is aligned with the printing region and the image content using the next segment of the linear printhead.

An apparatus and method configured to eject an electrically charged liquid. The apparatus and method include a liquid-ejecting apparatus including a reservoir for storing a liquid, an electrically conductive faceplate for ejecting the liquid, a plurality of channels connecting the reservoir to the electrically conductive faceplate, and a voltage source to change and maintain an electric potential difference between the liquid and the electrically conductive faceplate during ejection from the electrically conductive faceplate.

This printing device is provided with a first ink container that contains a first ink; a second ink container that contains a second ink; temperature adjusting units that adjust the temperature of the first ink contained in the first ink container and/or the temperature of the second ink contained in the second ink container; a nozzle that sprays the inks; and a control unit that controls the first temperature adjusting unit and the second temperature adjusting unit.
