Thanks Jon, I will try that.
I'm curious abut the P2 curves you supply for download. (I am looking in the curves folder for x800/x880 printers using Warm Neutral inkset). When you created those curves, did you find that they all responded well to 30000 units of GO? Or did you find some needed more GO than others?
When I look at the amounts of ink used in CurveView, I see the p2 master curve has a higher maximum (34) in the Y channel (where my shade 1 is) than the Y curves for most of the baryta surface papers, like Photo Rag Baryta, FineArt Baryta, Exhibition Fiber, Canson Baryta. Curves for those papers are around 12 in the Y channel.
The Y channel values on Type 5, Photo Rag Pearl, seem closer to the master curve, and I haven't had the gloss differential in the blacks happen as much (or at all) on Type 5 or Photo Rag Pearl.
