RE: (1) Gum over Cyanotype on sized Masa paper (rough side) - (2)Pigment that makes gum insoluble w/o exposure?
Thanks, I cut back PV19 too much (+ cut back the exposure by 2/3 stop)
because I was afraid of ruining the print again (it would be the 3rd in
a row if I had ruined that too!)... Next time will try the same (and
maybe a lower dichromate concentration) with slightly more PV19 (it's a
"crazy" colorant, too little makes too much -> very similar to phtalo
blue - which I also have)...

Transparent colors should give you a neutral color balance just as
easily as opaque ones, if not moreso, because there's a clean mix of
the colors overlaying. It's hard to tell from the screen, but I
would have said your print has a blue-green cast. More PV19 should
neutralize that; did you try printing with a little deeper
concentration of that? Transparent doesn't mean wimpy, as my website
comparisons of transparent vs opaque pigments demonstrate.
