bubbles in gelatin
Hi all, especially all gummists,
I've been sizing some paper for gum that's too big to handle in usual way,
that is, by pulling paper out of tray pressing between soft plastic rod &
tray edge to squeegee off excess gelatin.
What's messier, but works sort of, is to stand large plate glass
vertically at edge of tray (leaning against wall behind sink), stick
gelatined paper on that & run rod lightly down the paper. The excess
gelatin sluices back into the tray. At first the bubble problem defeated
me completely -- for some reason far worse than by usual method. Then I
added about 2 ounces of rubbing alcohol to remaining litre of (3%)
gelatin. Big help to extent that I could squeegee the front
satisfactorily, but pulling the sheet off the glass still left serious
bubble lines on the back. And with the big wet sheet in hand, no way I
could smooth that.
Meaning the back of the paper is unusable -- tho normally (I confess) I
print on back of a failed print on good heavy paper. I remember reading
about some anti-bubble solution (other than alcohol) & wonder if anyone
can say which. Kodak used to make one, but discontinued as of probably 10
years ago....
Or maybe up the ratio of alcohol (except that I reheat between batches on
the stove, and fear inviting explosion) ? Any other advice out there?
Hopefully,
Judy
