I must have missed the original post since I don't know what this and the
clip that preceded it refers to.  But if it is a way to measure the color
difference in gray ink and papers I don't think there is a single number
that does it.  Best bet is a spectral comparison of a fifty percent patch
with a reading from a grayscale card.  But that doesn't tell the whole story
since each light color impacts the result.  However, assuming a standard
light source, and using ColorShop's spectral comparison we could get a delta
e reading between a gray card and any ink/paper combo.  But quite frankly
this sort of numerical comparison doesn't do much for me - not broad enough
to get the true understanding of tinted appearance.  Possibly a set of
readings compared to the gray patches on a Macbeth chart would be good.
