Was this resolved? I'm getting excellent b&w prints on HP Pro Satin, but I'd be interested in comparing to a quad print if in fact this paper isn't printing b&w with all 4
The quad black is only available for the matte papers as it uses MK, PK, MG, LG and you do not want a matte black on gloss paper. I guess that it is also a wise decision by HP not to use PK on matte papers when the coating isn't optimal, the partioning with the PK included can only get some enhancement in the shadows, the density of the PK is much closer to that of the MK than to the MG ink. At least that has been my experience when I used a similar arrangement on my Epson 9000 with QTR and a MIS quad set.
I get 1.73-1.74 Dmax on HM PhotoRag (Bright White). Media profile chosen is Thick Fine Art paper>250 gsm and calibrated. On top of that I use a by the Quadtone Rip profiler created QTR RGB B&W profile. Printing from Qimage + the Advanced B&W mode of the HP driver. That is higher on HM PR than I could get with my Epson 9000 and 10000 loaded with MIS Eboni black, the last is considered a very good matte pigment ink on HM coatings.
While the Litho realistic media profile gives a wider color gamut on HM PR it is less in Dmax.
A RIP may be able to get near 1.8 Dmax but usually that will be the max possible, the more recent barite like generation (more satin) being the exception.
