Methinks you crazy Bill!
Word on the street is that Kodak's matrix film had some unique polymers in it; not just pure gelatin. (or perhaps it was collagen I'm thinking of?)
Are the raised relief portions areas of high silver content; high-lights on the negative?
I'm thinking that since there was no etch, you might be dealing with more of a Pinatype/planographic-matrix situation, where you have a differential of tanned & untanned gelatin, as opposed to a true relief matrix where you only have tanned gelatin and the untanned has been etched away. If that's the case then you might find that your dyes don't allow for clean highlights.
But, this is all hypothesizing!
