There may well be improvements you can make in your inkjet negatives, but
part of what you are seeing is very likely the greater resolution of the
silver-gelatin paper as compared to most hand-coated processes. Commercial
photo paper is coated on very smooth stock that has been precoated with a
bright white barium sulfate ("baryta") layer that is polished smooth. It
can show much more detail than salted paper or Pt coated on even a very
smooth paper surface. Don't get me wrong, I love Pt prints and have
probably made nearly as many of them as I have made prints on commercial
photo paper. But at their "best" -- I mean, their most technically perfect
-- their resolution falls far short of a good baryta-coated silver-gelatin
print. (As an aside, I have tried various methods to make Pt prints on
baryta-coated paper, hoping to get the best of both worlds -- or at least
something interesting -- but so far with little success.)

Also, your Grade 0 paper is still significantly more contrasty than most
hand-coated processes, further accentuating the "grain" of the negatives.
