First, thank you all for your answers on sulphite and wood pulp. MOST helpful and I learned more than I was asking (e.g. photo paper, bast and seed, etc.).
So I did a cut and paste and edit of McClain’s website and compiled a list of the papers and thought it could be of use to the list.
Keith, I have found Hosho, Kitakata, and Okawara a bit fragile for my tastes in comparison to other delicate papers I have preferred (Masa, Thai Kozo, Awagami Gampi), but they were all from Legion, not McClain’s. Have you tried any of the papers below and nixed them because they disintegrated in water or something? Abraded easily?
When I was in Japan a number of years ago I bought a bunch of paper (one sheet as high as $60). Unfortunately I didn’t keep the names of the papers so they don’t do me much good in my paper testing bout now, but some of those papers printed poorly in cyanotype and some also disintegrated like a paper napkin in water. Of course I know we subject paper to a more rigorous process than a wood block or other printmaking process, but it would be helpful to eliminate any of the below that don’t work so I don’t have to reinvent the wheel. Wow, though, I think I will avoid the $43 per sheet papers :)
BTW I can do all this testing with abandon because cyanotype is so cheap but I feel for you, doing it all with pt/pd chemistry :)
Group A Washi Paper
This group of Washi includes our finest printmaking papers. They are all entirely handmade, with deckle edges on all four sides. The papers are medium to heavy weight, of high fiber content, tear beautifully, and all are acid free.
A great paper with a subtly brushed texture and the translucency of more fragile papers, Nishinouchi is surprisingly strong. Tears exceptionally well. Sized, handmade (four deckle edges) 60 gsm, 90% kozo 10% acid free pulp, 15.60 29.25 $41.75
Kizuki Hanga off white 27x40.5
An exceptionally low price for a 100% Kozo paper of this weight. The slightly off-white shade creates an excellent background for sharp, luminous, clear colors. Sized, handmade (four deckle edges), 135 gsm 100% kozo $43.85
Kizuki Hosho Natural 18x21.5
The Echizen districts's famous printmaking Washi, created by Living National Treasure Ichibei Iwano. 100% Kozo of the highest grade. Smooth surface; unsized, handmade (four deckle edges) 75 gsm 100% kozo 27.30

Group B Washi Papers
These versatile papers are of very good quality. They are either handmade, or partially so, from a mixture of fiber and buffered, acid free wood pulp. Of medium-light to heavyweight, recommended for serious students and professional printmakers on a budget.
Torinoko Light Weight-Cream 24x35.75 $10.75 50 gsm 70% gampi 30% mitsumata
This very uniform, fine fibered handmade paper is translucent and soft to the touch. An exceptional bargain for paper this well made and containing such a high percentage of Gampi, a fiber that is becoming increasingly rare in Japan. Tears exceptionally well. Sized, handmade (four deckle edges).
Torinoko White, Cream 25x37 145 gsm 70% Mitsumata, 30% pulp $17.60
Very smooth on one side and fairly rough on the other. Traditionally you print on the smooth side, but either side can be used. Sized, machine made (no deckles)
Group C Washi Paper

Group D papers
These papers are mostly unsized, and have diverse fiber content. They range from pH 6.5 to pH 7.5 (pH 7 is acid free).
Usu Mino off white 21.5x31, 25 gsm, 70 mitsumata 30 acid free wood pulp $2.95
A very thin, lightweight mending tissue that can be used for tracing as well as transferring printed images from the key block to color blocks. Sized, machine made (no deckle).

You might also be interested to know that there is a hand-made dosa-sized paper called Masa available from McClain's Printmaking Supply <http://www.imcclains.com/catalog/paper/groupc.html> that is very nice.

>> Thanks for checking on this, but I’m still unclear on one important detail.
>> Can you ask Doug if 100% sulphite or 100% high alpha cellulose is lignin free? I thought I read that these removed lignin. The reason I ask is there are some high end papers that have these ingredients now and Masa is one that is 100% sulphite. And I don’t know a lignin from a hole in my head so it’d sure clarify it for me :)

>>> Below is info from Doug Ishimura of IPI on lignins forwarded with his permission:
>>> Lignin has been a very big issue in the deterioration of photographs. Even the Fading Committee of 1855 noted that poor quality mount boards were a cause for fading photographs.
>>> In the 1960s and again in the 1980s, lignin from poor quality cardboard microfilm boxes were implicated in the formation of red spots or redox blemishes on microfilm. These spots are a form of silver image deterioration. As it turns out, the lignin, a complex, undefined organic molecule, generates peroxides as it breaks down. It also produces molecules that are referred to as chromophores that cause staining of the gelatin and albumen in photographs.
>>> Peroxides are bad because they can remove electrons from silver converting image silver to mobile, silver ions (silver oxidation) and can provide electrons to convert silver ions into elemental silver atoms (reduction). This wouldn’t be a problem if both events occurred immediately together, but they don’t and the silver ion has plenty of time to migrate away from the silver image particle where it originated.
>>> The result that we see is yellow/orange/red staining of highlights and mid-tones, silver mirroring, fading, and red spots.
>>> The photographic activity test in ISO 18916, which is required in the enclosure standard, ISO 18902, looks for both staining of proteins such as gelatin and albumen and silver particle oxidation or reduction.

>>> Subject: DOES LIGNIN CONTENT IN PAPER KEEP IT FROM BEING ARCHIVAL?
>>> DEAR DOUG,
>>> Does lignin content in paper keep it from being archival? I seem to recall that we used 100% cotton paper for our hand made prints because it was lignin free.
