I am no expert, but did you consider the possible limits of ink and paper combination? E.g. matte papers do not produce so rich black like glossy ones. My matte papers produce lab value around 15, if I recall correctly. I am not sure to which extent the black would become darker if I start playing with the ink limits. Searching the web confirmed this value, hence I take it as a limit. best regards, -- Milan Knizek knizek (na) volny (tecka) cz http://www.milan-knizek.net/
