    • A medium is carried to a predetermined position in a carrying direction. A first pattern is formed on the medium with nozzles on the carrying direction upstream side of a nozzle row constituted by a plurality of nozzles lined up at predetermined intervals. After forming the first pattern, the medium is carried in the carrying direction by a target carry amount that is shorter than the length in the carrying direction of the nozzle row. Along with forming on the medium a second pattern that forms a boundary with the first pattern with nozzles on the carrying direction downstream side of the nozzle row, a third pattern is formed on the medium with the nozzles on the carrying direction upstream side of the nozzle row. After forming the second pattern, the medium is carried in the carrying direction by a target carry amount that is shorter than the length in the carrying direction of the nozzle row so that a carry amount of the medium after forming the first pattern is longer than the length in the carrying direction of the nozzle row. A fourth pattern that forms a boundary with the third pattern is formed on the medium with the nozzles on the carrying direction downstream side of the nozzle row.
    • 将介质沿着携带方向传送到预定位置。 第一图案形成在介质上,在喷嘴列的输送方向的上游侧具有喷嘴,喷嘴列由以预定间隔排列的多个喷嘴构成。 在形成第一图案之后,通过比喷嘴行的输送方向上的长度短的目标搬运量,将载体沿运送方向运送。 随着在介质上形成与喷嘴列的输送方向下游侧的喷嘴形成与第一图案的边界的第二图案,在介质上形成第三图案,喷嘴在喷嘴的输送方向上游侧 行。 在形成第二图案之后,通过比喷嘴排的输送方向上的长度短的目标搬运量将介质沿运送方向运送,使得形成第一图案后的介质的进位量比 在喷嘴列的传送方向上的长度。 在介质上形成与第三图案形成边界的第四图案,喷嘴在喷嘴列的输送方向下游侧。

    • A printing method includes determining a first correction value corresponding to a first print mode, determining a second correction value corresponding to a second print mode, and correcting an ink ejection amount of each row region individually, using a combined correction value obtained by combining the first correction value and the second correction value. The first print mode is a print mode that is applied to a front end area, with respect to a transport direction, of a medium. Dot rows are formed extending in a nozzle movement direction that is perpendicular to the transport direction, on a plurality of row regions lined up in the transport direction. The dot rows are formed by repeating a movement ejection operation of ejecting ink onto the medium while moving nozzles in the movement direction, and a transport operation of transporting the medium in the transport direction. The first correction value is for correcting an ejection amount of the ink in each row region individually. The second print mode is a print mode that is applied to a middle area, with respect to the transport direction, of the medium. The second correction value is for correcting an ejection amount of the ink in each row region individually. The correction of the ejection amount using the combined correction value is carried out in a coexistent segment in which certain row regions and another row regions are coexistent. The certain row regions are row regions in which the dot rows are formed by the first print mode. The other row regions are row regions in which the dot rows are formed by the second print mode.
    • 打印方法包括:确定与第一打印模式对应的第一校正值,确定与第二打印模式相对应的第二校正值,以及使用通过组合第一打印模式获得的组合校正值来单独校正每个行区域的喷墨量 校正值和第二校正值。 第一打印模式是应用于媒体的相对于传送方向的前端区域的打印模式。 在沿输送方向排列的多个行区域上沿着与输送方向垂直的喷嘴移动方向形成有点列。 点列是通过重复在移动方向上移动喷嘴的同时将墨喷射到介质上的移动喷射操作形成的,以及在传送方向上传送介质的传送操作。 第一校正值用于单独地校正每行区域中的墨的喷射量。 第二打印模式是应用于介质相对于传送方向的中间区域的打印模式。 第二校正值用于单独地校正每行区域中的墨的喷射量。 使用组合校正值的喷射量的校正在其中某些行区域和另一个行区域共存的共存段中执行。 某些行区域是其中通过第一打印模式形成点行的行区域。 其他行区域是其中通过第二打印模式形成点行的行区域。

    • A printing method for printing an image on a medium according to the present invention includes the following steps: printing a correction pattern based on a first gradation value by ejecting ink from a plurality of nozzles moving in a predetermined movement direction and forming a plurality of dot lines in an intersecting direction that intersects the movement direction; obtaining, for each dot line, first information corresponding to the first gradation value by measuring a darkness of the correction pattern dot line by dot line; and printing an image constituted by a plurality of corrected dot lines on the medium by correcting each dot line in accordance with the first information and second information corresponding to a second gradation value that is different from the first gradation value.
