One of the allied projects is testing a much wider range of papers than I was using previously.
This currently includes Awagami Inbe (Japan) and papers from Cartiere Magnani (Italy) and Lana (France).
As results come through I will post if the list is interested.
Well it's over a year, so about time I posted something.
At the time I wrote the above I was trying various papers with the photo black in the Epson K3 . inkset. None of the above came out well , with DMax quite low. The matte black ink improves approx 0.3 n DMax. Of coated matte papers I am currently using, DMax is between 1.5 and 1.6 for Hahnemuhle Photo Rag; Crane Museo, Museo II, Max; Awagami Bezan and Okawara;and Lana Lanajet In general the smoother the paper the wider the gamut, but once profiled the differences are really only apparent with files wider than Adobe GRB (1998). Okawara is a beautiful random fiber handmade paper with a pronounced texture (not pattern, like the machine made papers), yet it still comes in at 1.54, with a white only 0.03 darker than HPR, which has OBAs.
Somerset Velvet comes in around 1.4 which is not too hot. What impressed me, and Les Walkling who did the hard sensitometry , was how well many of these papers came out. Most of the profile modification was necessary in the cool colours , especially cyan. This is an ink problem, not a paper one, thoughit should be said Hahnemuhle Photo Rag performs very well and currently forms the technical standard for matte papers. I hope to test on a HP Z printer to see if this assists in the cyans. The fourth black may push the DMax further.
We have also tested other papers such as Schutt and Buxton , but these are special purpose papers, and not really of interest to most people on this forum.With dynamic range and colour gamut comparable for many papers, and here I also include Arches, BreathingColor and Moab, the choice will be often on how a particular surface complements an image. Cost is also a signficant factor with handmade papers running around 8x good machine made papers.
It's like everything else really...
