Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a penetrating and drying type printing ink which can suppress shrinkage (thinning) of a rubber roller and a blanket at a printing machine to the utmost even when it uses both a non-aromatic petroleum solvent and a vegetable oil which hardly pollute the global environment and a workplace. SOLUTION: The printing ink comprises 1-20 wt.% of a sucrose fatty acid ester obtained by ester interchange of sucrose and a fatty acid derived from natural oils and fats, 10-60 wt.% of a vegetable oil and 0-40 wt.% of a non-aromatic petroleum solvent in the total weight of the printing ink containing a pigment, a resin for varnish and a solvent.
