I just printed a 1400 HP-PK black only test strip on some old 
Kirkland glossy paper.  With QTR I was able to get a dmax of about 
2.4.  The tones are shown in this Lab A & B graph:

The reflective artifacts are minimal.

With normal reading glasses, I can't see individual dots, but I do 
get a sense that it's not totally smooth.  Even with a magnifier, I'm 
not seeing any microbanding.

So, although I can't say anything about clogging or other issues that 
might crop up, it looks like it'll work quite well.

I'd had 30% HP-PK mixed with 70% C6 base in that spot, sitting idle 
and next to the Eboni, in the yellow spot, for about 3 weeks.  All 
inks had a perfect nozzle check after these two inks had been sitting 
idle for this amount of time.
