Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a printing method reproducing a color region wider than a color reproduction region of RGB expressed by conventional yellow, red, blue and black process four-color printing. SOLUTION: In infiltration drying type offset printing using two or three of yellow, red and blue ink and a black ink, the yellow ink is one for infiltration drying type offset printing containing 5-15% of a disazo yellow compound, the red ink is one for infiltration drying type offset printing containing 15-20% of a metal lake compound of a rhodamine dye, and the blue ink is one for infiltration drying type offset printing containing 0.7-2.0% of a phthalocyanine compound, which are used in combination in the infiltration drying type ink.
