Abstract
The present invention relates to an ink-jet printing method that is capable of obtaining good printed materials that are free of occurrence of color migration and deformation of a printing medium even when printed on a resin printing medium. The present invention provides an ink-jet printing method using a water-based ink containing a black ink, a chromatic ink and a white ink which each contain a pigment (A), an organic solvent (C) having a boiling point of not lower than 90° C. and lower than 250° C., and water, said method including step 1 of ejecting at least one water-based ink selected from the group consisting of the black ink and the chromatic ink onto a transparent resin printing medium to print an image 1 on the printing medium; step 2 of ejecting the white ink onto the resulting image 1 to print a white image that covers the image 1 on the printing medium; and step 3 of heating and drying the resulting printed material from a side of a surface of the printing medium on which the white image is formed, using an infrared heater.
