摘要： A sharp image is formed without variation in ink spreading around an outer periphery of a print-required region depending on a printing direction. At the time of printing an image by scanning a print medium with a print head for ejecting a first ink which is visible as black and has relatively high permeation properties of penetrating the print medium and a second ink having relatively low permeation properties, a printing apparatus uses the second ink to print on at least an edge area of the print-required region of the print medium, and the first ink to print on a non-edge area surrounded by the edge area. The print head comprises a first nozzle array ejecting the first ink and second nozzle arrays ejecting the second ink. The second nozzle arrays are arranged on opposite sides of the first nozzle array in the scan direction.

摘要： An ink jet head is provided which includes: a piezoelectric board having a plurality of elongated channels arranged parallel to each other and isolated from each other by channel walls; and a nozzle plate having a plurality of nozzle holes provided in association with the respective channels, and bonded onto the piezoelectric board with the nozzle holes located at generally longitudinally middle positions of the respective channels; wherein the nozzle plate has trench-like recesses each having a predetermined width and a predetermined depth and extending perpendicularly to the channels as being spaced equidistantly from the nozzle holes longitudinally of the channels; gaps for communication between adjacent channels are defined by the recesses between a surface of the nozzle plate and upper face portions of the channel walls located equidistantly from the nozzle holes; and active areas contributable to ink ejection are defined in each of the channels on opposite sides of the corresponding nozzle hole along the channel. This arrangement prevents deterioration of ejection characteristics attributable to bonding offset of the nozzle plate, and suppresses residual vibration occurring due to pressure waves without complication of the construction of the ink jet head, thereby ensuring stable ejection characteristics even in high speed driving.

摘要： An ink jet printing apparatus is provided which can form sharp images while maintaining high grayscale levels even if the images include various kinds of image constitutional elements to be printed by image data having different attributes, such as character, fine line and image data. This invention checks attributes of the input image data corresponding to the image constitutional elements making up the images and also detects edge and non-edge portions of the image constitutional elements. Further, this invention generates print data for printing the edge portions and print data for printing the non-edge portions based on attributes of the input image data corresponding to the image constitutional elements.

摘要： In a binarization process employing dot arrangement patterns, the deviation of formed dots is prevented from occurring. Specifically, the arrangements of the dot arrangement patterns of each of four planes, which correspond to the groups of the four species of dot arrangement patterns of one certain level of five-valued data, are determined. In a process for determining the arrangements of the dot arrangement patterns of the four planes, the repulsive potential between the dot arrangement patterns in each plane and the repulsive potentials among the dot arrangement pattern in one plane and the dot arrangement patterns in the other planes are computed. Besides, the arrangements of the dot arrangement patterns of the planes are determined on the basis of the results of the repulsive potential computations.

摘要： It is an object of the present invention to detect whether or not a conveying path is in a state capable of discharging a recording medium, having a recorded image thereon, outside of the apparatus, so as to prevent generation of a jam in conveyance and discharge of the recording medium. A state of covering a discharge port by a cover member is detected, and image recording on a recording medium is executed only when the recording medium can be conveyed and discharged. Non-execution of recording is indicated to an operator, and execution of recording is resumed when the cover member is moved to a state not obstructing conveyance and discharge of the recording medium.
