Re: tri-color gum in progress

LOVE the poppy and the little hairy stem...
PS thanks so much for the glyoxal test.  I have some more things to talk about yellowing that totally dovetail with your tests so it is exciting.  However, one thing that is definite is that the yellowing NEVER washes out once there in my lengthy experience with yellowing, so a method that you have devised of using the least amount to prevent this is really exciting to me. More on this later--I have book reviews to write :(

Subject: tri-color gum in progress

I promised some scans of gum in progress. This illustrate the indanthrone (PB60), nicke azo yellow (PY150) and either perylene maroon(PR179) or quinacridone rose (PV19). Well, as you can see I never make things simple. I like to add two blues (indanthrone and thalo), two different magentas (current examples are PR 179 and PV19) and often different yellows. This might be accompanied by selective use of masked negatives or spot color negatives of just separations with different contrast.
