Abstract
The present invention relates to an ink-jet printing method using an apparatus including a printing means for ejecting a black ink to a printing substrate to print characters or images on the printing substrate, and a drying means disposed on a downstream side of a transportation direction of the printing substrate, in which the printing substrate is a label printing substrate; the black ink is a water-based composite black ink; the water-based composite black ink contains a composite black pigment containing carbon black, and a content of the carbon black in the composite black pigment is not more than 25% by mass; and the drying means is an infrared heater for heating the water-based composite black ink ejected onto the printing substrate to a temperature of not lower than 95° C. and not higher than 125° C. According to the ink-jet printing method of the present invention, it is possible to obtain a good printed material that is free of color migration or deformation of a printing substrate even when printed on a label printing substrate.
