Patent ID: 8454152

Claim:
An ink-jet recording device comprising: a conveying section which conveys a recording medium in a conveying direction; a head section which is equipped with a plurality of full line type ink-jet heads arranged in the conveying direction of the recording medium, each ink-jet head jetting an active energy ray curable ink having a different color with each other to the recording medium; and a semi-curing light source which is located between the ink-jet heads and semi-cures a first ink jetted from the inkjet head located in an upper stream of the conveying direction of the recording medium and landed on the recording medium before a second ink jetted from the ink-jet head located in a downstream of the conveying direction of the recording medium is landed on the first ink, wherein the following conditional expression (1) is satisfied: 0.6 ≦R/R 0≦0.9, conditional expression (1) provided that: R is a dot radius of the second ink jetted on the first ink which is jetted on the recording medium and semi-cured; and R0 is a dot radius of the second ink directly jetted on the recording medium; and wherein the ink-jet recording device further comprises: a judgment print output device which outputs a judgment print produced by superimposing a dot image of the second ink on an image of the first ink having a plurality of areas which differ in an irradiation energy amount of the active energy ray with each other; and an irradiation energy amount setting device which sets up one irradiation energy amount by selecting the one irradiation energy amount between the minimum amount and the maximum amount in a plurality of irradiation energy amounts used for producing the judgment print so that the conditional expression (1) is satisfied, the one irradiation energy amount being referred to at the time of recording.
