Digital BW, The Print

I've looked at the MIS site and through the archives here for the
actual density of the MIS FS inks but I've come up empty.  I apologize
if this has been asked before but can some kind soul please either
point me to the info or describe the FS ink's densities?

I think that the MIS VM inks are 15%, 25%, 45%, 50%, 75% and 100%.  Is
this close?

Thanks,

Richard Cooke
