Patent ID: 7878642

Claim:
A method of producing an image comprising the steps of: (a) ejecting droplets of at least two actinic radiation curable ink-jet inks from an ink-jet recording line head so as to deposit onto a recording medium; and (b) irradiating the deposited droplets of the actinic radiation curable ink-jet inks with actinic radiations, wherein the two actinic radiation curable ink-jet inks being different in hue with each other; and an absolute value of a difference of ΔS(S low −S high ) between the two ink-jet inks different in hue is 5-1,000 mPa·s, where S low represents a viscosity of the actinic radiation curable ink-jet ink measured with a share rate of 11.7 l/s at 25° C., S high represents a viscosity of the actinic radiation curable ink-jet ink measured with a share rate of 1,000 l/s at 25° C., and ΔS(S low −S high ) represents a difference between the viscosities of S low and S high , wherein ΔS(S low −S high ) of the actinic radiation curable ink-jet ink firstly ejected and deposited on the recording medium is larger than ΔS(S low −S high ) of the actinic radiation curable ink-jet ink secondly ejected and deposited on the recording medium, provided the firstly ejected ink and the secondly ejected ink are different in hue.
