@Furthering you can go two approaches, first there are inks that are so-called “drier” which won’t bleed as much on a bigger range of papers. R&K Salix or Pelikan 4001 Blue-black are ones to look into.
On the other side, if you want to find better paper, there are many good choices available in Europe. Clairefontaine—French paper is very good (Moroccan paper less so, but not bad), Midori MD, Fabriano.
If buying in larger quantities you could consider Clairefontaine DCP or Kokuyo KB paper.
