Abstract: In an inkjet head which has nozzle rows having nozzles each of which ejects curable inks cured by imparted activation energy and which are arranged in a first direction at a pitch P, the nozzle rows being N (N≧5) nozzle rows of every color which eject, respectively, thick inks of four colors including cyan, magenta, yellow and black, and at least one light ink among light inks similar in color tone to the thick inks, the nozzles in each of the nozzle rows are arranged so as to be shifted by P/N from each other in a first direction, a nozzle of an ink with lowest cure sensitivity is arranged on the most upstream side in a direction of relative movement of a recording medium in the first direction, and further the nozzle of light ink is arranged in between the nozzles of two different thick inks.

Abstract: An inkjet recording method of the present invention includes preparing an inkjet recording apparatus having an inkjet head that has N (N≧4) nozzle arrays, so as to respectively discharge inks of at least four colors of cyan, magenta, yellow and black, having nozzles arranged in a first direction at a predetermined pitch P for discharging a curable ink which is cured by providing active energy, each of the nozzle arrays is arranged to be shifted in the first direction so as to have distances of more than 0 among each virtual line extending from each nozzle in a second direction perpendicular to the first direction, in which the viscosity of any of the respective inks at 25° C. is 10 to 30 mPa·s.
