Katherine:
I was about ready to have a bonfire last week after a bout with the
speckles. After letting my blood pressure drop, I had a better session
yesterday by carefully inspecting each sheet by holding it up against a 60
watt light and carefully looking for any specks. I rejected about 1 in 4
sheets and had minimal problems this time. Still a few tiny spots
occasionally, but all fixable.
If this paper didn't make such great prints, I'd have ditched it long ago.
It appears that bits of something are falling into the paper when it is
made, because almost all of them appear to be within the paper itself. The
lesson learned: check very carefully before spreading anything on this
paper.
It makes a great gum-over paper if only one gum layer is contemplated.
