PCT No. PCT/EP96/00173 Sec. 371 Date Oct. 15, 1997 Sec. 102(e) Date Oct. 15, 1997 PCT Filed Jan. 17, 1996 PCT Pub. No. WO96/24046 PCT Pub. Date Aug. 8, 1996A color measuring device measures the light transmitted through the material to be measured as well as the light reflected therefrom and the irradiated light and measures the color reflectivity in the various spectral ranges by dividing the reflected intensity by the difference between the irradiated and transmitted intensity. The calculation of the color reflectivity in the individual spectral ranges is thus corrected to the proper extent without the need to place color tiles behind a transparent material to be measured. |
