<P>PROBLEM TO BE SOLVED: To provide an active energy ray-curable inkjet printing system which causes little density unevenness and gloss unevenness and is excellent in curability and to provide its image forming method. <P>SOLUTION: In the active energy ray-curable inkjet printing system, a plurality of active energy ray-curable inks which are cured by active energy rays are delivered onto a recording medium by a plurality of recording heads 3, and then the active energy ray curable inks are cured by radiating active energy rays so as to form images. In this inkjet printing system, a plurality of the active energy ray irradiating parts are composed of two or more LED light sources LED 1 and 2 having different light emission characteristics. A plurality of the active energy ray curable inks are composed of two or more inks having different hues, and the composition of a photo polymerization initiator group contained by at least one of the inks has a composition that is different from the photo polymerization initiator group of the other ink. <P>COPYRIGHT: (C)2009,JPO&INPIT |
