One other small point that you may already be aware of:  be sure that you are in fact laying down "black" values.  Use the histogram tool in PS (hold down the control key while you move the slider) to see where the black pixels are. You may find that a vanishingly small number of pixels are actually near 100%.   

Somewhere on the piezography site there is a nice tutorial showing how to steepen the curve from about 90-100% to push more pixels into the deep blacks. Perceptually it can make a big difference.  Good luck.

Whereas it seems clear that the other papers are increasing in density right up to 100% load.  Well, maybe not that interesting.  It's why we need to profile the papers, afterall.  Right?
