Hi Peter,

Yes, there are some that don't size but you may get staining issues. Also,
when stretching and developing you may lose some of the manufacturers size.
It is gum compatible because it has a good wet strength and is dimensionally
stable.

I use FAEW HP, sized with gelatine and have put down 7 or 8 layers on one
image. I'm with Loris here on the thickness of your layers. I find I can get
a very thin layer by coating with a foam brush and then using a dry foam
roller to even out the coating.

John,

The paper is Fabriano Artistico Hot Pressed Extra white. I did not use any
additional sizing. I believe that the manufacturer is internally sizing it
with AKD, which does a pretty good job .AFAIK some gum printers add their
own sizing to this paper while others do not because it is very "gum
compatible" right out of the box.

Regards,

Peter Friedrichsen
