Digital BW, The Print

I'd like to make sure the wat you partition when 2 same inks in the 
printer.

Say M and LC are loaded with the same ink. Once you have set M relative 
to K, M Limit should read 50 and then LC "copy curve from" M Limit 100.

For instance :

M     Gray ink          Density 32   Limit   50
LC    Copy Curve from   Density M    Limit  100

Am I correct in this ?

Thanks.
