Re: Seeking Information on 2 problems with Gum process

Marek, Mike, Chris, Diana, Peter --

Thanks all for the pointers, suggestions, and advice.

I had investigated Thayer's site and didn't find quinacridone
rose (which I had already run across) and under pthalo blue it says this pigment is not happy with cad. yellow, which is often recommended -- Now -- does that statement refer ONLY to mixing the two together, or is printing one on top of the other affected? After, the last 24 hours of reading, I'm guessing that once it's hardened in gum, it doesn't matter. But, then if you want to make a green from a blue and yellow, you should find some other happier pair.

I'm esp. grateful to Peter Blackburn for the elegantly simple idea of dabbing the paper of use with each color, letting it dry and then washing it off to observe the strength of its staining.

Exactly. I am a born fiddler but I know that you need a foundation from which to start. That's what I'm looking for here.

The print I made yesterday using the cyanotype as a first pass (Sam Wang) worked wonderfully well -- except the cyanotype was too perfect!! i.e. too dark -- so today I'm going to severely lighten it and try again.

Again, thanks to all for all the help.
