I make "enhanced copies."
I take the article, which is usually on page 12 of section D, and put it on the front page. if there is a jump page (on page 20) I can reposition it to the front page, too, and arrange the columns so they make sense. (Something the newspaper are unable to do.,)
I enlarge it to obscene proportions and reduce everything else on the page.
I clean up the inevitable smudges, adjust the color and contrast on the photo and print the whole thing on archival paper with pigmented inks.
For commercial customers (the ones that usually have this kind of work done) I can insert their logo in a prominent spot.
I charge more for the Photoshop and printing work than I do for the framing. And, can you keep a secret?, it's fun.
No personal experience that I can recall with Archival Mist, but I've had mixed results with We Tu. You have to evenly saturate the paper, after which it always looked a tad green to me.
