What is worse then: a fading of all the greys proportionally or having a
black that will fade more than the greys ?

It has been mentioned here before in parts but it would be nice to see a
summary of the mixing ratios  (ratia?) for different quad sets and the resp.
density values for a given paper. Would that be possible ?
