摘要： A present invention reduces the generation of periodic uneven print density in the image in a main scanning direction. The present invention focuses attention on a fact that, when a printing head including a plurality of nozzle arrays for ejecting different inks is used to print an image and when the same pixel is printed by a combination of nozzle arrays in which an interval in the main scanning direction is relatively short, the displacement of ink impact positions is smaller when compared to a case where the same pixel is printed by a combination of nozzle arrays in which an interval in the main scanning direction is relatively long. Thus, a dot arrangement pattern allocated to the pixel data is selected so that the same pixel is printed by a combination of nozzle arrays in which an interval in the main scanning direction is relatively short.

摘要： In an ink jet printing apparatus using many types of inks to execute bidirectional printing, when symmetrically arranged ejection opening rows for a cyan, magenta, and yellow inks are used in the print head, one-pass bidirectional printing is executed. On the other hand, if ejection opening rows for a black ink are used in addition to the above ejection opening rows, multi-pass printing is executed so that there are a number of dots formed with one application order for the black and other color inks and the same number of dots formed with another application order for the black and other color inks. This reduces the non-uniformity of the colors attributed to the difference in application order.

摘要： For a serial color ink jet printing apparatus that forms an image using a symmetric printing head that ejects large dots and small dots, the configuration of a printing head is provided for suppressing, to the extent possible, a cyclic fluctuation in the main scanning direction. According to the present invention, individual nozzle arrays are arranged so that two nozzle arrays, i.e., a cyan nozzle array c1 and a magenta nozzle array m1, that are located nearer each other, form dots on adjacent scan lines. With this arrangement, a high quality image, having neither an uneven density nor an uneven color, can be formed when a printing head is inclined, or when a cyclic shift in printing positions occurs, depending on the position of the main scanning direction.

摘要： An inkjet recording apparatus suppresses defective ejection while reducing a consumed ink amount. In the apparatus, a cap-open period, during which a cap member does not cap ejection ports of a recording head of the apparatus, is measured, and a recovery operation executed by a recovery unit is controlled based on a cumulated cap-open period. With the above arrangement, there can be solved a problem that the ink ejecting state of the recording head is deteriorated depending on a recording operation because a cap-open state, in which the cap member does not cap the ejection ports of the recording head, continues while the inkjet recording apparatus executes the recording operation, thereby the reliability of the inkjet recording apparatus can be improved.

摘要： A liquid applying apparatus can prevent an applying liquid from evaporating while an applying operation is stopped and can reliably prevent the liquid from leaking even when, for example, the posture of the apparatus is tilted. An abutting member of a holding member is abutted, under an urging force of a spring, against an applying surface of an applying roller. Thus, a liquid holding space is formed between the applying roller and a holding member to hold the applying liquid. The abutting member is annularly formed of a single member. The applying roller rotates to cause the applying liquid held in the holding space to adhere to an outer peripheral surface of the applying roller. The applying liquid is then applied to the applying medium.
