An inkjet recording apparatus includes: a treatment liquid deposition device which deposits a treatment liquid insolubilizing or aggregating inks of a plurality of colors, onto a recording medium; a recording head which has a plurality of nozzles ejecting the inks onto the recording medium on which the treatment liquid has been deposited; a data acquisition device which acquires density data of an image with respect to each color, the density data corresponding to the plurality of colors; a higher-order color correction device which corrects the density data, wherein when the inks of different colors are ejected in ejection order so that a preceding ink ejected precedingly to form a lower layer and a subsequent ink ejected subsequently to form an upper layer overlap each other, the higher-order color correction device corrects the density data for a nozzle ejecting the subsequent ink according to the density data for a nozzle ejecting the preceding ink; and an ejection controller which controls ejection of the inks from the recording head according to the density data that the higher-order color correction device has corrected in such a manner that the image is formed on the recording medium.
摘要:
An image formation device that inspects for image irregularities caused by joining of inkjet head modules. The image formation device is equipped with a belt conveyance unit, a recording head, a print sensor and a system controller. The belt conveyance unit moves paper in a conveyance direction. At the recording head, modules including plural recording elements that eject ink droplets are joined up to a length corresponding to the width of the paper. The recording head ejects ink droplets at the paper being conveyed to form an image. The print sensor reads the image recorded on the paper, while moving in the width direction of the paper. On the basis of the image that is read, the system controller inspects the quality of the image recorded on the paper.
