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).

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