Digital BW, The Print

I have not done a K only curve but will be doing so in the coming days.  For
the hue of the K, here's some numbers for you.  Calibration chart K ink line
at 50% on HPR308:

Step 5: 78.0 0.1 -2.1
Step 15: 52.5 -0.5 -2.9
Step 25:  36.2 -0.6 -3.0
Step 35: 25.8 -0.3 -2.7
Step 45: 19.1 0.2 -2.3
Step 55: 14.6 0.7 -1.9
Step 65: 12.2 1.1 -1.7
Step 75: 10.4 1.4 -1.4
Step 85: 9.3 1.6 -1.5
Step 95: 9.0 1.6 -1.4

Of course that's not linearised or anything and I would limit K at 45% (and
just boost to 50% if at all).  It gives you an idea of the hue though (paper
white 97.5 0.7 -1.3).  Relatively cool which I personally don't like.

Like that dMax of 2.0?  These inks, while looking and feeling dry out of the
printer, will drop two big figures of L* overnight and it seems like some
more over another 24 hours. Please oh please let them have decent
longevity...
