Abstract:
1. A method of forming an image comprising: a step of heating a nonporous substrate to a temperature in a range of from 30° C. to 80° C.; and a step of forming an image on the nonporous substrate by applying water-based inks of at least two colors to the nonporous substrate employing an ink jet technique, wherein an ink set that includes water-based inks each comprising a coloring material, an emulsion resin, water, and a water-soluble solvent is used to apply the water-based inks of the at least two colors, wherein amongst the water-based inks in the ink set, at least one water-based ink has a minimum film-forming temperature different from those of water-based inks of other colors, and wherein the water-based ink having the lowest minimum film-forming temperature has a minimum film-forming temperature 5° C. to 10° C. lower than that of another ink of another color, amongst the water-based inks in the ink set.
