ABSTRACT:
The present invention relates to a method for fluorescent image formation which can form a highly scratch-resistant fluorescent full-color image using a colorless fluorescent agent and can freely regulate the tone of color mixture of a combination of two or more fluorescent colors in order to impart, to articles, a higher level of forgery preventive function than a prior art technique and a print having a high level of forgery preventive function. The invention characterized in that fluorescent inks are provided that are substantially colorless upon visible light irradiation and contain organic fluorescent agents which, upon ultraviolet light irradiation, emit fluorescences in a visible region, and that two or more fluorescent inks, which emit fluorescences having mutually different color tones, are deposited on a printing face in its image formation region according to information on an image to be printed in a dot matrix manner so that dots of one color do not overlap with dots of another color.
