PROBLEM TO BE SOLVED: To clearly decide a color measured value of a color material used for a printer in real time. SOLUTION: A color material is a combination of primary color materials exceeding two kinds, and the light from a light source 38 passes through a color material mixture or is reflected from the color material mixture to be received by a sensor 40 having a comparatively small number of light detecting mechanisms 50. The respective light detecting mechanisms 50 have different transmissive primary color filters on them. Accuracy of a spectrophotometer can be approximated by using a comparatively simple light source by using various special algorithm. |
