摘要： To provide an ink jet printing apparatus and ink jet printing method capable of printing at high speed and high image quality in accordance with the distance between the head and the paper. In performing a first print mode for printing to a unit region of the print medium by making the print head scan N times (N: positive integer), and executing a second print mode for printing to the unit region of the print medium by making the print head scan M times (M: positive integer, M>N), the distance between the print head and the print medium (distance between the head and the paper) in the first print mode is made shorter than that in the second print mode.

摘要： The invention prevents a pattern arising from periodicity of dot arrangements from appearing as noise, such as a streak, when a plurality of different dot arrangements are used repeatedly in a unit of a predetermined number of the dot arrangements for the same level of gradation of input image data, and thereby makes it possible to print a high-quality image. To this end, when input image data quantized to one of multivalued levels of gradation is allocated to a dot arrangement of M×N, a matrix of A×B created by combining a plurality of different dot arrangements each displaying the same level of gradation of the input image data in a raster direction and in a column direction is used as a minimum unit, and the dot arrangement of this matrix is allocated to the input image data.

摘要： To achieve high-quality printing by controlling an ink-travelling direction by an electrostatic force so that the ink can be accurately applied on a printing medium, the ink is landed on a desired position of the printing medium effectively without disturbing the ink ejection, independent of a difference in the thickness of the printing medium. An electric field between a printing head and the printing medium is generated by applying a voltage to a platen of conductive material positioned immediately below the printing medium. At this point, the voltage applied to the platen is adjusted so that the electric field of a preferable intensity can be generated on a face of the printing head where ejection openings are formed irrespective of the thickness of the printing medium.

摘要： To achieve high-quality printing by controlling an ink-traveling direction by an electrostatic force so that the ink can be accurately applied on a printing medium, the ink ejected to areas outside edges of the printing medium is prevented from being attracted to the end portions in margin-less printing. This configuration includes: a platen, made of a conductive material, positioned immediately below the printing medium; an absorber positioned at a side of the edge; and a mesh conductive member disposed on the absorber. A first voltage is applied to the platen, causing polarization in the printing medium, and a second voltage higher than the first voltage is applied to the conductive member. Thereby, ink ejected outside the edges in the margin-less printing, travels straight-forwardly toward the conductive member without being attracted to the end portions, and is absorbed into the absorber via the conductive member.

摘要： When thinning processing is performed to reduce the occurrence of black stripe caused by an overlap between scanning areas that is designed to prevent an end deviation from causing a white stripe, dots printed in a predetermined region by not only an ejection opening array subjected to the thinning processing but also other ejection opening arrays are counted so as to obtain their respective printing duties. Then, a color gamut is obtained based on the printing duties of the respective ejection opening arrays. Then, a thinning rate of the ejection opening array subjected to thinning processing is obtained by referring to a table corresponding to the color gamut, based on the printing duties of the respective ejection opening arrays obtained as above, and the thinning processing is performed. Accordingly, thinning processing can be performed which accurately reflects an amount of actual end deviation.

摘要： For a horizontally arranged print head, in which nozzle rows are arranged parallel with a scanning direction of the print head, two of a plurality of ink colors used, which have the greatest hue difference, are selected. Between the nozzle rows for these two colors, at least two nozzle rows for other colors are arranged so that the nozzle rows for the two colors have a large inter-nozzle-row distance. The resulting print head is used for printing. If cyan, light cyan, magenta, light magenta, yellow, and black are used as ink colors, the light cyan, black, yellow, and light magenta inks are arranged between the cyan and magenta inks, having a great hue difference.

摘要： An ink jet recording apparatus is structured to perform discharges in the capping status when preliminary discharges are performed in a shot number larger than a predetermined number, and perform discharges in a cap or a preparatory port other than the cap when the preliminary discharges are performed in a shot number less than the predetermined number. With the structure thus arranged, it is made possible to implement the suppression of the mist generation due to the preliminary discharges, and to make the time of recording on a recording medium shorter as well.

摘要： In an inkjet printing apparatus capable of automatic duplex printing, time required to fix ink is shortened and throughput is improved without producing uneven fixing. The inkjet printing apparatus includes a printing unit that prints onto a sheet, a fixing unit that heats a sheet printed by the printing unit, a conveying unit that conveys a sheet with respect to the printing unit and the fixing unit, and a controller that controls the conveying unit such that a printing region of a sheet printed on the first side by the printing unit passes through the fixing unit, and afterwards, the conveyance direction of the sheet is reversed in order to print on the second side and the printing region once again passes through the fixing unit. The controller variably controls the conveyance speed of the sheet when the printing region once again passes through the fixing unit.
