Claim 6:
7. The method of claim 6, wherein the reference value includes a normalized scattering intensity of light emitted from the ink and a standard deviation value of the normalized scattering intensity when the first light and the second light are irradiated to ink having different particle concentrations,
the acquiring of the data on the first exit light and the second exit light comprises acquiring normalized scattering intensities of the first exit light and the second exit light and standard deviation values of the normalized scattering intensities, and
the calculating of the concentration of the particles in the ink comprises calculating the concentration of the particles in the ink by comparing the normalized scattering intensity and the standard deviation value of the reference value with the data on the first exit light and the second exit light.
