Re: Attn Tor re flat drying of w/c paper
Hi Tor, Gelatine can be quite difficult to control and needs quite a bit
of practice to control it. The method you have from the shop seems to be
succesful and I will certainly try it. But I am surprised that you had no
problems with the transference of image ( Gum ? ) to the top pressure glass.
Or was it another process ? Then again, '' a very tiny amount of water''
and, '' the felt absorbes the water in the paper'', as you describe do not
seem compatible.
I hope your success with this paper flattening system
continues.
See you again in two weeks after the holiday.

Hi John,
I was not particulary successful with your method, as the gelatine got
quite messy and didn't seem to dry properly when being in direct contact
with the glass. After asking in a nearby art store, I was however
suggested trying the following process and I get pretty good results:
Let the paper dry "in air" and ripple all it would like. Then apply a very
tiny amount of water to the back side of the paper, just to moist it
slightly. I use a simple spray flask for this. Then place the paper with
the back side onto a piece of printing felt (a rather thick piece of
cloth), then a piece of glass and some heavy books on top of that. The
moisture makes the paper flexible again and the ripples are "pressed" out.
At the same time, the felt absorbs the moisture in the paper and after
several hours, the paper is mostly dry, nice and flat.

Tor, After processing you need to allow the paper with the image to dry
thoroughly, of course. Then coat the back of the paper with 5% gelatine,
The dry gum image is not so delicate. Place the print on the PLEXIGLASS.
Lay an interleaving sheet of paper on the print. Then a sheet of thick
cardboard. Apply the weight (maybe a heavy book or a couple of house
bricks or a five litre bottle of liquid or whatever) and leave until
dry. A screw down book press would be the ideal thing to use but they
are rare, nowadays. Anyway, you dont really need one.
Look forward to hearing about your trial.
Till later.

idea
to me. First of all, at least the gum print surface is very delicate and
easily damaged and I would expect weights, at least on heavier papers,
to leave marks?
