Color density value evaluation method for color printed material has wavelength used for calculating color density values determined from measured remission spectral values

摘要

The color density value evaluation method uses simultaneous photoelectric measurement of the different color density values for several measuring fields (2-5) of the color printed material (1), with detection of their remission spectral values at defined time intervals, for determining a wavelength for calculation of the color density values by using the remission values which remain approximately constant.
