Re: spots and fish eyes

Dave et al,
     No sizing. I have never had this happen before, but I will admit I
don't use Fabriano usually. I will admit I was not great about interleaving
the sheets when preshrinking this time, as I left for the darkroom and they
sat in the water a while. I bet it is what Jack is saying, as it is like
the paper is rejecting the gum at that point. It is exactly as Katharine
describes--the gum when painted on "opens up" in circles.
     Actually, I remember when I was attempting different dilutions of
acrylic size and at one point I had this happen, and someone on the list
(Dave S?) was saying that at a certain point of dilution the....viscosity or
something...was broken or some such thing. But that is a different
topic--these are not sized.
     Anyway,Katharine, I'll take you up on the black spotty gum print and
jpeg it to you now.It really is quite interesting. OH, I should say they
aren't black, just dark.
     I should give Fabriano the benefit of the doubt; it was a stack of
paper I had cut a year or two ago. I normally use Rives and like I say, have
never had problems with either black spots or fish eyes...in fact, I have
never seen this before ever. I could blame it on the water, but this has not
happened with Rives since I've been here so I don't think that is it.
     You know what??? I wonder if it isn't the flip side of the fish
eyes--this one has the paper accepting too much pigment perhaps???
