Re: fogged digital negative?
I have been storing my digital negatives in a print box, either right
after printing it, or right after making a print with it. So I really
haven't been letting them air dry much at all - at least not in any
intentional way. I've now reprinted the ones I would like to print
with again and have placed them on a shelf in a closet to dry - with
the ink side up. I won't be able to do any printing for the next two
weeks, so I'll just let them dry out a few days, then put them in
sleeves until I have time to print again in a couple of weeks. To be
safe, I think I'll let them air dry a bit after printing also, before
returning them to their sleeves.
Thanks again for all the good information. I hadn't given much
thought to the negatives, so this has all helped a lot.

My experience is that you can use digital negatives a number of
times until the get scratched or you do something that wrecks them.
I've used them up to 10 times and have not noticed any problem from
the exposure to UV light.
If I understand correctly you used this negative before and it
sounds like it picked up moisture from the coated paper this time.
Did you notice having to peel the two apart?
Newly printed negatives will look "frosted" when viewed from the non-
emulsion side until they dry a bit. This is very pronounced right
The 2200 inks take much longer to dry than the current inks in the
R2400. As Jon mentioned, you can give the negative a boost in
drying with a hair dryer without damaging it, as long as you keep
the hair dryer moving and don't overheat the negatives.
For the 2200, I think the negative would cure in a couple of hours
on the original Pictorico and in less time on the Ultra Pictorico.
An R2400 negative on Ultra is cured in about half and hour the the
density remains stable after that.
The R1800 negatives take quite a while to cure and are prone to
picking up dust during printing and right after. The 2200 and
current inks don't seem to gather dust at all.
I always let my negatives cure emulsion side up.

I was printing some cyanotypes today and one of my digital negatives
seems to have "fogged". I've printed with this negative 3-4 times
before, with fairly consistent results. But today it added a dark
ring around the print. When I looked at the negative, it looked OK
the inkjet side, but the other side had a strange, silvery fog to it.
The effect was to lighten the negative and print out darker around an
area about 6 inches in diameter.
Is this a normal problem for a digital negative - a short life span?
Or did I do something wrong - maybe use it too soon after printing
negative. I don't remember how long I waited before using it to make
a print. But I've used it several times over several weeks. I'll
make another negative, but just wanted to check here to see what I
have done wrong. The negative requires a 9 minute exposure for the
cyanotype and paper I'm using. I'm printing with a UV lightbox
around 26 x 20 inches or so, and about 4 inches from the bulbs.
