<p><P>PROBLEM TO BE SOLVED: To provide a printing method, which has more excellent reproducible color rendering region (gamut) than those obtained by the Japan color conforming inks in ISO standard and by the conventional active energy ray curable inks and enables the reproduction of wider color rendering region than ever in a printing method employing four process colors such as highly saturated yellow, red, indigo blue and black excellent in color reproduction and by employing green ink also. <P>SOLUTION: In the active energy ray curable ink, in which either two, three or four inks among yellow ink, red ink, indigo blue ink and green ink and black ink are employed, five colored blended active energy ray curable ink is employed, respective L*a*b* values of the standard density values on the L*a*b* colorimetric system (according to JIS Z 8729) of which fall within specified ranges when printing is executed under the condition that the density range of red is set to lie within the range of (or employed as a standard density value) 1.40-1.44, that of red of 1.52-1.56, that of indigo blue of 1.63-1.67 and further that of green of 1.45-2.15 as the indigo blue density. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
