<p>PROBLEM TO BE SOLVED: To obtain a spectral characteristic which is equal to that of complementary color cyan by controlling the pigment where the color index is C.I. pigment blue is 15:4 and the pigment where the color index is C.I. pigment blue is 36 to the particular film pressure by mixing them in the particular volume ratio. SOLUTION: The first pigment, C.I. pigment blue of 15:4 and the second pigment, C.I. pigment blue of 36 are mixed in the volume ratio of 1:(1 to 5)and a film pressure is set to about 500 to 1500nm. For the wavelength of 450nm, the transmissivity is set to about 60 to 75% and for the wavelength of 575 to 600nm, the transmissivity is set to about 40%. Thereby, the spectrum characteristic of the pigment-based complementary color cyan (C) becomes almost equal to that of the staining-based complementary color cyan (C).</p> |
