Problems solved by technology

[0007] Placing each color head as described in Japanese Patent Application Laid-Open No. 2007-118409 will cause enlargement of the bracket supporting the color heads as well as the UV irradiation light source, which in turn causes degradation of scanning speed and increase of power consumption

Abstract

In an inkjet head (24, 110) 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 (12, 120) in the first direction, and further the nozzle of light ink is arranged in between the nozzles of two different thick inks.

Description

field of invention [0001] The present invention relates to an inkjet recording apparatus and a method for controlling the inkjet recording apparatus, and more particularly, to a technique of ejecting inks of a plurality of colors to form an image. Background technique [0002] In a conventional inkjet recording apparatus, nozzles of respective color heads are arranged so as to be aligned on the same line in the main scanning direction so that arrangement positions of ink dots of respective colors can be shared. [0003] When such a nozzle arrangement is applied to an inkjet recording device using UV curable ink (ultraviolet curable ink), ink dots of all colors are arranged on the same line by one main scanning action. Therefore, these ink dots may cause landing disturbance in the main scanning direction, and undesirably form a linear surface shape with large depressions and projections. Slight shape differences due to these depressions and protrusions make the uneven glossi...
