Is the density of the black on its own that relevant ? The minimum
L* value of the final profile will depend mainly on your TAC.
Even with a setting of 220%, the total CMYK minimum L* value
should be enough for nearly any normal (reflective print) situation.
(Of course "weird" ink formulations may break this - some ink formulations
have the effect of getting lighter beyond a certain point of adding
CMY to black. This seems to be media dependent as well.)
I can't remember a situation in which we had to reject a printing
device with a K density of >= 2.0 because it failed to be able to match
the target minimum L* value.
