    摘要： Provided is a print position control method whereby displacement of a print position in a wide range can be corrected very accurately, without reducing a printing speed or increasing a manufacturing cost. Thus, a printing apparatus includes: a first correction unit, for correcting a print position at accuracy equal to the resolution of the printing apparatus; and a second correction unit, for correcting the print position at accuracy higher than the resolution and in the range of an area that corresponds to one pixel of the resolution. With this arrangement, the print position displacement in a wide range equal to or greater than one pixel can be corrected by the first correction unit, and a print position displacement smaller than one pixel can be corrected by the second correction unit. Therefore, correction of a print position displacement in a wide range is enabled at a higher accuracy.

    摘要翻译： 提供一种打印位置控制方法，可以在不降低打印速度或增加制造成本的情况下，非常精确地校正大范围内的打印位置的位移。 因此，打印设备包括：第一校正单元，用于以与打印设备的分辨率相等的精度校正打印位置; 以及第二校正单元，用于以高于分辨率的精度和对应于分辨率的一个像素的区域的范围来校正打印位置。 利用这种布置，可以通过第一校正单元来校正等于或大于一个像素的宽范围内的打印位置位移，并且可以通过第二校正单元校正小于一个像素的打印位置位移。 因此，可以更高精度地进行宽范围内的打印位置位移的校正。

    摘要： When a printing position is displaced by an inclination of a printing head, for example, the displacement can be corrected in an easy and effective manner and a user can easily recognize the displacement of the printing position to correct the displacement. To realize this, dots for forming a test pattern are formed by different scannings by a nozzle group including a plurality of nozzles positioned at one end side of a nozzle row and a nozzle group including a plurality of nozzles positioned at the other end side of the nozzle row. Depending on displacements of the printing positions of these dots, the plurality of nozzles constituting the nozzle row are divided into a plurality of divided nozzle groups. Then, the printing position is adjusted on the basis of the divided nozzle groups.

    摘要： Image deterioration is suppressed as much as possible which is complexly generated by variations of printing positions respectively of printing elements in a printing element row and by displacement of printing positions among printing element rows. To this end, a first adjustment value for adjusting printing positions among a plurality of printing elements included in a printing element row is obtained. Next, printing positions among a plurality of printing elements are adjusted based on the first adjustment value. Then a second adjustment value for adjusting printing positions among not less than two of the printing element rows is obtained. Thereby variations of printing positions in a discharge port row and displacement of printing positions among discharge port rows are properly adjusted in different phases, and adverse effects generated by two kinds of different causes are collectively suppressed.
