Add here the paper specifications: whiteness of paper weight, emulsion 
(without or gloss emulsion, etc.), paper additives, etc.

I know at least 10 different blacks that can came out of print (all are 
100%K). Beware that printing industry is probably one with least standards. 
Even if there are some, they're hard to achieve.

The always applicable hint: Be good (really good :) ) with your printer and 
ask for directions while designing.

Sorry for popping in...
