摘要： An ink jet recording apparatus performing recording by discharging ink from a recording head onto a recording medium. A conveying belt for conveys the recording medium by the attraction of static electricity, an electrode contacts the recording medium conveyed by the conveying belt, and a power source charges the electrode with a charge having a polarity opposite to a charge carried by the conveying belt. The recording head includes a discharge port and a control electrode formed around the discharge port. A voltage identical to the polarity of the surface potential of the recording medium is generated by a power source and applied to the control electrode to cause the control electrode to repel any satellite droplet of the polarity identical to the voltage that splits from a discharged ink droplet during the flight thereof.

摘要： An apparatus for performing the printing by scanning a carriage having a plurality of print heads mounted in a predetermined direction relative to the printing medium, so that an image is formed to have a desired color tone and density without decreased throughput. Conversion data for reproducing the color tone and the scan range of the carriage are changed in accordance with the used heads among the mounted heads. Also, the replaceability can be enhanced and the longer life for each group is attained by grouping the heads mounted. Further, the scan range of recording and the scan range for the recovery can be changed by selecting the group for use in accordance with the recording mode. Also, in an ink jet printing apparatus having a longer print length, a printing method for effecting the stable recording is provided.

摘要： An ink-jet printed product is formed by printing an image with a plurality of similar color inks having different concentrations and a special ink having a single concentration. In the product, graininess resulting from ink dots is decreased for all hues of the printed image. A decision is made as to whether or not a hue of an image to be printed can be printed with inks without the special ink of a color (for example, special color BL (blue)) having a single concentration. When it is decided that the hue of the image is to be printed with inks without the special color ink, data on ink color BL (blue) is decomposed into data on C (cyan) and data on M (magenta). The hue can be printed without the color BL, thereby significantly decreasing graininess in a portion having this hue.

摘要： An image recording apparatus records an image on a recording medium by causing a recording head having an arrangement of a plurality of recording elements to conduct its main scanning for the recording medium interrelatedly in the direction opposite to the arrangement of the recording elements. The apparatus comprises a setting device to set the number of main scannings by the recording head; a main scanning device to perform recording by plural numbers of main scannings with respect to one pixel by causing the recording head to conduct its main scannings for the same recording area of the recording medium in accordance with the number set by the setting device; and a sub-scanning device to cause the recording head and the recording medium to be sub-scanned interrelatedly per main scanning in an amount smaller than the width of the arrangement of the recording elements of the recording head. Hence, even if a disabled ejection occurs in one scanning at the time of recording by a multi-scanning, the missing dot is complemented by the following scan to make it possible to obtain an image having no image defects at all times.

摘要： An object is to provide ink jet printed products superior in the image quality such that ink jet printing onto the cloths satisfy the various conditions regarding the density, resolution, and graininess of dot. To accomplish this object, when an image is formed by a number of dots obtained by discharging the ink from a print head to attach the ink onto the cloths, the ink amount discharged from the printing head onto the cloths is controlled to produce ink jet printed products so that the average value of equivalent circle diameter for each dot after image formation may be three-fourths or less the average value of diameters of fibers constituting the cloths. Thereby, ink jet printed products excellent in image quality can be obtained with blurs reduced and high graininess of dot.

摘要： An ink-jet printer for printing an imaging using an ink-jet head has a heater for holding the temperature of the ink-jet head above a predetermined temperature. The temperature of the ink-jet head is held above the predetermined temperature at the time of a recording operation. When the recording operation ends, elapsed time from the end of recording is measured and, when elapsed time attains a predetermined time, current fed to the header is stopped. From this point onward, the temperature of the ink-jet head is held at a temperature below that which prevails at the time of recording until the next recording operation begins.
