Digital BW, The Print

Just wondering what your thoughts might be on these guidelines. I've had some positive conversations with them and I explained the advantages of carbon ink printing. I didn't see that technique listed here, but they did end up accepting carbon b/w prints. They used to accept only archivally processed darkroom prints.

Please note especially the inks and paper they approve, on page 3. I realize this is a b/w group, but I gather one of the reasons we like b/w prints is for their archival qualities.

Any thoughts?

Thanks,

PS I started a thread on this a couple of years and the responses were very helpful. But I don't recall addressing this particular question.
