  • Colorant identification method and colorant identification apparatus
    Patent number: 8964175
    Abstract: Distribution is acquired for a reflectance spectrum and a fluorescence emission spectrum on a sample composed of color-image recorded matter. Then, on the basis of the distribution of the reflectance spectrum and the fluorescence emission spectrum, a single color portion is identified that is generated with one colorant selected from colorants of plural colors used in generating a color image. A control unit stores in advance Raman spectra of colorants of single color for each manufacturer. Laser light is projected onto the single color portion of the sample so that a Raman spectrum is measured. Then, the measured Raman spectrum is compared with the Raman spectra stored in advance so that the manufacturer of the colorant is identified and hence the colorant is identified.
