can anyone reccommend a fix for this problem with gelatin size? i'm having
the fish eye problem something awful. it seems on my last print i was able
to coat over it with some tenacity, but when i cleared the print there was
a dark spot of pigment/gum over that spot. luckily when i took a brush to
it it mostly disappeared.

this problem comes from too much size? how much is too much size? my sizing
method is basically livick's, although i size both sides of the paper by
dipping the paper into the gelatin/glyoxal bath and then i hang it to dry.
that way there will be less subsquent curling of the paper (with both sides
sized).

so, what is too much size?

cheers,

Steve
