Abstract:
1. An ink-jet recording apparatus which jets an ink onto a recording medium to perform a recording, comprising: an ink-jet head in which a plurality of nozzles, through which the ink is jetted, are formed; a scanning mechanism which reciprocates the ink-jet head to perform scanning of the ink-jet head in a scanning direction; a transport mechanism which transports the recording medium in a transport direction perpendicular to the scanning direction, and which includes a plurality of nip sections, each of which is arranged with a spacing distance therebetween in the scanning direction and nips the recording medium to transport; and a controller controlling the ink-jet head, the scanning mechanism, and the transport mechanism to perform the recording on the recording medium and including a pattern forming mechanism which controls the ink-jet head to jet the ink onto the recording medium from the nozzles in a forward scanning and a backward scanning of the ink-jet head, so that a pattern including a mark for detecting a relative position deviation, in the scanning direction, between a landing position of the ink in the forward scanning and a landing position of the ink in the backward scanning is formed, wherein the pattern forming mechanism controls the ink-jet head to form a part of the mark in one of areas of the recording medium transported by the transport mechanism, the areas including a first overlapping area which overlaps in the transport direction with one of the plurality of the nip sections or one of outer areas which are placed at outside positions of outermost nip sections, among the plurality of nip sections, which nip the recording medium at outermost positions on both sides in the scanning direction, respectively, wherein the plurality of nip sections include spurs and rubber members, and wherein the pattern forming mechanism controls the ink-jet head to form the pattern so that the part of the mark is formed in the first overlapping area and an adjacent area that is adjacent to the first overlapping area but does not overlap in the transport direction with the rubber members, and so that the mark is not formed on a line which extends in the transport direction and is equidistant from the one of the nip sections and another nip section next to the one of the nip sections.
