Abstract: The present invention provides a colorimeter apparatus for a color printer ink capable of rapidly measuring the colors of a color patch portion in an online mode. The light of a xenon light source 21 is directed via an optical fiber 22 and a condenser lens 23 to a zone through which a color patch 53 passes. Reflected light is condensed by a telecentriclens system 14 and focused on the light-receiving surface of a Linear Variable Filter 11. The light is spectrally divided by the Linear Variable Filter 11 and guided toward a linear sensor 13 via a fiber optic plate (FOP) or collimator 12. The output of the linear sensor 13 is converted to an analog signal by an analog signal generator 14 and sent to a signal processor 3. In the signal processor 3, a spectral reflectance factor is calculated based on the resulting spectral reflectivity, and a color or color difference is calculated based on this value and a prestored formula for color systems or color differences.
