摘要： The present invention reduces image deterioration such as density nonuniformity when recording is performed using a recording head having two ejection orifice rows that eject a predetermined achromatic ink, for example, gray ink. For this purpose, the distance between two ejection orifice rows that eject a predetermined achromatic ink is larger than the distance between two ejection orifice rows that eject a predetermined chromatic ink.

摘要： An ink jet printing apparatus is provided which is capable of producing an image with a good balance between image quality and printing speed, without unduly shortening a longevity of a print head, even when an odd-numbered-pass bidirectional printing is performed. To this end, during a bidirectional multi-pass printing with a relatively small number of passes, a stepping mask is used to eliminate image problems caused by a difference in print permitted ratio between forward scan and backward scan. During a bidirectional multi-pass printing with a relatively large number of passes, a flat mask is used to give priority to suppressing density unevenness resulting from nozzle characteristic variations. As a result, the printing apparatus as a whole can produce an image with a good balance between image quality and printing speed, without unduly shortening a longevity of the print head.

摘要： Even if an error occurred in a result of the detection by an optical detecting mechanism for optically detecting whether or not a remaining amount of ink in an ink tank is equal to or less than a predetermined amount, a correct situation of the remaining ink amount in the ink tank can be detected. A detecting method has a first discriminating step of discriminating whether or not a remaining ink amount in the ink tank is equal to or less than a predetermined amount by using an optical sensor and a second discriminating step of discriminating whether or not the remaining ink amount in the ink tank is equal to or less than the predetermined amount on the basis of information regarding an amount of ink consumed in the ink tank. If the absence of ink is determined in either the first or second discriminating step, information showing the absence of ink is notified.

摘要： A smooth, uniform image is produced by minimizing the occurrence of satellites of secondary color and dispersing landing positions of the satellites as uniformly as possible. For this purpose, the printing operation performed so that satellites of the two inks (cyan and magenta ink, foe example) ejected toward the same pixel are separated and landed on opposite sides of the main dots on the same pixel. This makes the distribution of satellites uniform and makes individual satellites less noticeable, maintaining the uniformity of an image.

摘要： A printing apparatus includes a plurality of print element arrays each with a plurality of print elements arranged therein. The printing apparatus prints an image by time division driving in which the plurality of print elements in each print element array are divided into a plurality of blocks and in which the print elements are driven for every block. The amount of misalignment among the print element arrays in an arrangement direction of the print elements is acquired. A print element group used for printing in at least one print element arrays is changed in accordance with the acquired misalignment amount to correct the misalignment among the print element arrays. A driving order of the blocks is changed in accordance with the misalignment amount. Even in the case of the time division driving, the misalignment of the dot formation positions can be eliminated.

摘要： In the ink-jet printing apparatus, the influence of displacements of printing positions caused by the excessive conveyance of a printing medium to the resultant image when the rear end of the printing medium exits from a nip portion between the roller pair in a conveying mechanism. More specifically, in the printing operation for the rear end portion of the printing medium in which the printing medium exits from the roller pair, the guide shaft for supporting the carriage is lifted at a position wherein a head-medium distance is changed to widen a distance between the printing had and the printing medium (S402). Thereby, the displacement of the landing position caused by the excessive conveyance of the printing medium is inconspicuous because of the variations of the landing positions due to the widening of the head-medium distance.

摘要： After a first scan in a forward direction, conveying corresponding to one nozzle block is performed, and then in a second scan in a backward direction, printing of a “printing area 1,” which is a unit area, is completed. Then after completion of printing of the unit area, conveying corresponding to 14 nozzle blocks is performed. Then by reciprocal third and fourth scans, printing of a “printing area 2” is completed in a likewise manner. Subsequently, two scans in a reciprocal manner are performed in a likewise manner to perform printing of each unit area. In any unit area, printing time intervals between scans are such that, at a same position in a scan direction, the time interval is the same. Consequently, differences in density between unit areas that are adjacent in a conveying direction of a printing medium, that is, between-band unevenness becomes more difficult to recognize.

摘要： An inkjet printing apparatus and method can efficiently feed printing media stored in a media storage unit, while at the same time minimizing the reduction in a printing speed during the ejection recovery operation. The ejection recovery operation is performed during a period extending from the end of printing for a preceding printing medium which is fed first by a feeding unit, to start of printing for a succeeding printing medium. The recovery operation is controlled at this time in accordance with a feeding condition under which the feeding operation performed by the feeding unit is determined.

摘要： A recording apparatus includes a recording unit configured to record a first dot and a second dot having a diameter smaller than that of the first dot on a recording medium, and a scanning unit configured to move the recording unit in a scanning direction. A recording resolution of the second dot in the scanning direction is lower than a recording resolution of the first dot in the scanning direction.
