Digital BW, The Print

I've been using Lyson quad black inks on my epson 1270 and printing on
German Etching Board available from digital art supplies. I think the prints
are beautiful and have been assuming from my early research into this that
they are archival prints - around 80 years. Does anyone dispute this?

In fact I've been so happy with these that I've been considering getting
into archival color, and from what I've read on the list it may be a good
idea to wait for the 2200 and see how it looks. Any feedback?
