Digital BW, The Print

Morning,

Has anybody used both the MIS and Generations Archival Inksets? and
if so, what are the basic differences? The New MIS double density black
is supposed to be very black, and is compatible with the MIS color
pigments....

I guess what I'm asking, is which is blacker, Beta Black from
Generations, or Double Density Black from MIS?

Thanks.

Jerry
