PROBLEM TO BE SOLVED: To provide an autogenously light emitting color image printing method, with which a printed material with a fluorescent color image having a color taste near to that of an original image without being influenced by the reflectance and color tone of a printing paper can be obtained. SOLUTION: After a solid printing with black ink 11 is executed on the printing region, on which characters or figures are printed, of the printing paper as a preceding stage for printing the characters or figures on the printing paper, the gradation regions printed with each of fluorescent inks, the gradations of which are different from one another by the fluorescent inks 12, 13 and 14, are formed. Next, by irradiating the gradation regions with the respective fluorescent inks with ultraviolet rays, the quantities of emitted light by the respective fluorescent inks are detected so as to calculate and store in a storage part correction coefficients for equalizing the quantities of emitted light by each of the fluorescent inks 12, 13 and 14 in the same gradation in order to fluorescingly display a plurality of the characters or figures by printing only dots of R, G and B selected among the characters or figures so as to obtain the predetermined fluorescent colors with the correction coefficients after reading the correction coefficients stored in the storage part at the printing with the fluorescent inks.
