Philippe, If the runoff is blue that means it's exposed, not underexposed,
and for whatever reason didn't soak into the paper. You could be using a
non-absorbent paper, or a gelatin sized paper (a no-no for cyano) it
doesn't sink in through, or maybe coating with puddle pusher, which also
tends to sit on top not absorb. Or possibly your emulsion is too fresh,
may wash off if it hasn't been aged in the bottle a couple of days -- or
that's the case with REGULAR cyano. I've never used the upgrade, which I
believe can be temperamental.
Or another thought -- are you heat drying the emulsion? That can dry it
as surface skin before it soaks into the paper, in which case it will also
wash off.
Of course the grand irony is that one reason Ware invented the "New
Cyanotype" was sight of blue down the drain. We never knew why because
around here it doesn't happen. Maybe it's something European? (Is Buxton
in Europe?)
best,
Judy
