Ok, so I just want to make sure that my post and thoughts are not
coming across as being ignorant or sarcastic about the possibilities
of these methods. I simply haven't heard/seen it yet.
Best,
Dario.

Looking forward to hear more about that as well.

Dario,
That's what I was afraid of. What you're saying is, after a
poster comes out of the deacidifying bath, if it is not immediately
backed that as it dries out the paper will wrinkle up like a prune,
right? Damn. I was hoping there was a secret technique for drying out
the poster after the bath which would allow it to end up wrinkle-free
without any backing. So much for my plan to "just deacidify" a bunch of
posters, then.
On the other hand, if this "starch backing" process really
exists and works as described, that could be the answer. As soon as
anyone gets some hard information on this "removable backing" process
please let us know!

Hi Randy,
I don't recall exactly were I read up on the wei'to buffer longevity,
It was a wile ago.
I do remember that this was discussed amongst book conservators and the
task of re spray libraries every 2-3 years, and even in some case due
to the large amount of books in some library's the spraying never stop.
Maybe it is an overly extra pre caution as book are constantly being
used/ handled, wile a poster re mains dormant in you drawer/tube what
ever you use for storage.
It would make sense, but then who realy knows at what stage your paper
is at ( PHV ) and how fast is it really deteriorating, unles you let a
restorer test the ph value on the poster.
I heard someone mention it on NS4 ( Starch Backing ) I know nothing
about it??? I am Stumped.
It's sound like a dream come through, if for real. I don't know if
restoration is possible with this method, Say paper re placement,
there is no foundation for the paper to attached to and if in painting
is needed it would be suspended in mid air???
I would inquire with John at PM see if it is for real and if resto is
possible, or if there is limitations.
Hi JR,
I Can dip and neutralize your posters for cheap, but without any
backing it would dry up looking like hell.
Press, Starch backing, weights, rolls I've heard a lot of things never
seen it.
I have experimented my self with a few ideas, but with mixed results.
Best,
Dario.

Dario, where did you get this estimate for the effective duration of a
Bookkeeper spraying? I haven't seen any scientific studies of this, and
without same, it's pretty much a guesstimate. Based on my admittedly
limited knowledge of the rate of acid formation in paper and the amount of
buffer laid down by Bookkeeper, I'd guess the effect would be much longer
than 2-3 years.
Of course, as you indirectly point out, what a surface spray doesn't do is
get the buffer deep into the paper substance. Paper may seem thin, but on
a molecular basis, there's a huge middle layer that the suspended buffer
won't reach, even when spraying both front and back.
AZ, there are instructions that come with Bookkeeper indicating how much
to apply. I apply it until the paper appears wet, but not so that there's
visible fluid on the paper surface, if that makes sense.
Another topic we might touch on here is a new technique I've been hearing
of lately that's supposed to be basically like easily-reversible backing.
The poster is deacidified in a bath and mounted on some backing material,
restored, and then the backing is easily removed without damaging the
poster, once it dries. So you get a beautifully restored poster without
visible fold lines and no backing. At least that's the theory. I've heard
this technique called 'starchbacking', which isn't a great name, imho.
Don't know much more about it, but Poster Mountain supposedly now offers
it, and I've heard of other restorers starting to offer this as well.
Anyone have any more details about this? If this catches on in a major
way, I could see traditional linenbacking decreasing in desirability in
the upcoming years.
Randy
