Hallo, greetings from Germany!
I make cyanotype prints for some years, using papers from "Arches"-
the simple ones, not Arches Platine.
I have no problems getting full range, using regular and fresh
emulsion.
But I need long exposure ( 1 hour in the sun).
By the way, when using fabric for cyanotype I have a yellow stain
in the lights.
Any idea how to avoid it?

Rainer
