Yeah--it is a **free** formula (fast) for the cyano techies on the list...I 
can think of a few. I find it so fascinating when people get into the 
chemistry of alt and devise weird things.  Maybe it's that yearning for a 
"back in the day" experience similar to what I read about in the BJP over 
and over.

I don't have a problem with bleeding with classic cyanotype either, but if I 
remember someone recently on the list did, though we thought it might be 
underexposure or the paper or not soaking in enough or low humididty or 
whatnot. OH wait, I might have had bleeding with it on Platine...and I 
certainly had huge bleeding problems with pt/pd on Platine. But it seems not 
much comes off at all when I use Fabriano Artistico.

Have no idea as I haven't tried it yet, having just received it.  Just 
shared it for interest, and at the rate I am going it'll be a while before I 
try it because it's down on my list of have-to's.  But it is supposed to be 
fast like the Rex.  Don't know how it compares to Mike Ware's version of 
Rex, either.  I am more tempted to try the cuprotype for the interesting 
color at this moment.
