Reflectance to Status A Density; How to convert?

  1. Mar 24, 2009 #1
    I have calibration data for some 0/45 reflectance standards which is in spectral format of %R in 10nm increments. I need to check the accuracy of reflection densitometers which read Status A density (V,R,G,B).
    What is the proper way to convert the spectral reflectances to density?
    Thanks,
    GR

    It doesn't look very compact, but it seems to be a well-posed problem:

    (Page 393). You will also have to convert your spectral data into an (RGB) format, which is also not simple but well-posed.
