I've been doing some three color gum printing, and it is going pretty well.
I thought I might try to print a cyanotype layer, and then print the magenta and yellow, ala Sam Wang and Christina Anderson.
Question: can the cyanotype be printed on already sized paper? Or do I need to print the cyanotype, then size, then print the gum layers? It seems the latter would be better, since the cyanotype does not sit on top of the paper like the gum layers. But I thought I'd ask for other opinions on this.
Thanks,

Steve, I print 1, 2, 3, and more colors over cyanotype and never size my paper. The paper I use is Canson Montval 140lb CP. Jim

Yes you can. I do it all the time. I use Fabriano Artistico Extra White or Rives BFK. Both are sized and hardened with glutaraldehyde. The papers are also preshrunk before sizing.
