Digital BW, The Print

I've touched on this subject before but I've never posted the link to the Regsiter's expanded policy: http://www.nps.gov/history/nr/policyexpansion.htm. They've also put forth a proposed update: http://www.nps.gov/history/nR/publications/bulletins/photopolicy/index.htm  (that second link doesn't always load well in my browser)

I'd appreciate it if some of you would look at their paper and ink suggestions. (the documents are lengthy but you can skip a lot of it and look for the paper and ink suggestions.) There's no mention of an all-Eboni approach which most folks here seem to think is the most archival - and I totally agree. Also, there's no mention of some of the other papers we all use and find to be very archival as well - papers with no OBA's, acid free and so forth.

In an earlier post I mentioned I had a positive exchange via e-mail with one of their staff and I explained I was proposing to use the 3MK method in 1800 and to use, I believe I said, Premier Art Smooth Hot Press Fine Art. This staff member approved of what I was doing, so I guess I'm on the right track. But doesn't it seem strange that they list inksets which use some color, and they list a paper, Epson Ultra Premium Presentation Matte which apparently (correct me if I'm wrong) uses OBA's and is not acid-free?
