    摘要: An ink jet printer is of a small size and is capable of printing high-quality images, wherein an ink with a colorant dispersed in a solvent is ejected in a direction lower than a horizontal level and is adhered to a surface of a recording medium. The recording medium is conveyed while being spaced a constant distance from ink ejecting electrodes, thereby stabilizing an electric field induced between the ink ejecting electrodes and the recording medium and stabilizing the amount of the ink ejected.

    摘要: An ink jet recording apparatus has a head substrate, a jetting member disposed on the substrate, a recording electrode disposed so as to sandwich the jetting member and for making ink jet from the jetting member, and a separating wall for covering the recording electrode, wherein the ink is supplied from the proximal end of the jetting member and recovered in an upward direction from near the tip end of the jetting member. According to such an arrangement, it becomes possible to prevent the recording electrode from being clogged with ink adhering at the tip end thereof, and thus, the locus of the ink drop jetted from the head can be prevented from being deviated due to deviation of the jetting point on the jetting member. Accordingly, it becomes possible to provide an ink jet recording apparatus which is capable of printing an image with a high definition.

    摘要: In a halftoning unit of a laser printer and the like, a high speed, high density and high gradations halftoning is realized by multi-value implementation by clustered dot concentrated dither halftoning (known as a sub-matrix method) and PWM distributing gradation among the plurality of halftone dots with a small memory and circuit. For this purpose, the value of the difference between an input gradation value ni and a threshold value nc, &Dgr;n=ni−nc, is shortened within a range of 0 to &Dgr;h and the lower s bit of &Dgr;h is removed by a round-down or round-up process. Meanwhile, a threshold array is generated from an extended threshold pattern obtained by combining threshold patterns of 2s whose threshold interval is &Dgr;h, i.e. &Dgr;Ah×K, &Dgr;h×K+1, . . . , &Dgr;×K+2(s−1). Thereby, a halftone dot dither process in which the PWM gradation increases distributively among the 2s dots may be realized with a small scale memory and circuit.
