RE: another 3 layer gum attempt



A less dense negative paired with more pigment maybe, or more dichromate and
more pigment... (The borders aren't dark in my screen, by my definition. I
don't take the darkest dark parts into consideration because it seems more
like pigment build up in the edges.)

Also, to darken you can try to print a 4th negative (the K from the CYMK
separation) with black pigment. Or, print each RGB negative once more with
black pigment using a higher contrast emulsion - because you need the
pigment only in the shadows... (And you don't want to totally block the
shadows.)

Many ways to slit the acacia tree right? ;)

I agree with Jim;   the color and value of the borders suggests that  
your pigment is adequate, but the negative is apparently keeping it from
printing as deep in the image itself.
