Generally the rule is: the cheaper and more absorbent the paper, the broader the ink line appears, because the ink penetrates more strongly into the fibre structure and spreads. Paper that is too absorbent, however, carries the risk that the pen cannot keep up with ink flow and skips, or that fibres get into the nib slit and create a brush effect. Strongly satin or coated papers, on the other hand, make the line appear narrower than it actually is, which is why the nib width chosen in the shop often appears disappointingly narrow at home. Recommended are mid-range premium papers such as Gmund papers, Cranes Crest (with cotton-like fibre composition like banknotes) and, as all-rounders, Zanders Gohrsmühle or Classic. Collectors advise always testing a pen with one's own usual paper, as the perceived nib width varies considerably.
