Digital BW, The Print

I am looking to invest in a Piezography system for glossy black and white printing. 
I’m primarily a film (Tri-X) shooter with access to a Hasselblad X5.

I’ve reviewed the information on the Inkjetmall site and still find myself a little confused in regards to the differences between K7, K6, P2. 

Piezography Pro is pretty clear, but Piezo Pro vs K7/K6/P2 in terms of image quality is another question. 

Going with Piezo Pro and having to do a second pass to apply the gloss is very tempting, but I wonder if the output from K7/K6/P2 is superior given that they use more shades of gray. 

Ultimately I would choose image quality over printing speed



Here is some additional information

- I have a new Epson P800

- Looking to print glossy and PiezoDN (PiezoDN should be fine with any Piezo set)

- I have no interest in printing matte.

- No interest in split tone printing (warm shadows with cool highlights etc)

- I am looking for the closest thing to a traditional selenium toned silverprint. Back in my darkroom days I used to print on AGFA Multicontrast and would selenium tone my prints. 

- Would choose image quality over printing speed.

- Am I correct in the assumption that High​ ​Density​ ​Photo​ ​Black​ is for glossy printing and UltraHD​ ​Matte​ ​Black​ is for matte work?

- I tend to accumulate material and print the project at once, so the printer may sit idle for some time. Sounds like Piezoflush will be my friend.


From my research is seems like I would want either a K7 or P2 setup. 

Is there a difference in quality / tonality / DMAX between glossy prints / DN made on the K7 system and Piezo Pro, given that K6/K7/P2 use far more shades of gray?


Perhaps someone can share their experience and point me in the right direction.


Thank you in advance,


Feli
