<p><P>PROBLEM TO BE SOLVED: To provide an active energy ray curable ink printing method, which enables a color reproducing region of RGB, used to be represented through five-seven color printing by adding a special color such as violet or the like in addition to conventional four process colors such as yellow, red, indigo blue and black, especially the color reproducing region of B (blue-violet) is made reproducible through double printing of indigo blue and red. <P>SOLUTION: This active energy ray curable ink printing method so excellent in highly saturated color reproduction is characterized in that double printing is executed in the two color inks, the chromaticities of which on L*a*b* colorimetric system (according to JIS Z 8729) in the density ranges of red at 1.52-1.56 and of indigo blue at 1.63-1.67 lies within specified ranges in the active energy ray curable ink printing method, and in that the chromaticities of the double printed part fall within specified ranges such as L* in 17-23, a* in 51-46 and b* in -71 to -76. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
