Thanks Mark...

I'll try doing the measurements in Lab instead of density. As far as improving the pre-linearization... Should I increase the point where the darker inks kick in... ie if full black is measuring at %90 change it to 95% and so on down the line for each ink? It sounds like I'll be burning through a lot of ink and paper.
