That was the first 21 step curve at 100%. I just wanted you to see 
what the black looked like at unreduced flow.

I set my limit at 55%, which gave me a "9.1" L value for the dmax on 
the PK when linerized. Just above where the inversion first seemed to 
occur around 8.7.

I also have to let my prints dry overnight or I can't linerize.

Here are the values that I think I linerized for a 4K+GLOP ink set on 
Epson Premium Semi-Gloss, with the 55% limit:

0	93.1
5	91.4
10	87.9
15	84.0
20	80.0
25	75.0
30	70.1
35	65.6
40	61.6
45	57.0
50	51.4
55	44.6
60	37.2
65	31.1
70	27.9
75	23.8
80	20.3
85	16.5
90	14.6
95	12.7
100	8.8

These were my settings for the "Grey Curve." But again, this was for 
a highlight biased ink set for portraits with GLOP:

	High	Shadows	Overlap	Gamma
Grey = 	75	10	15	1.5


And my density and limit settings:

PK = 	55 density overall	
LK = 	40	70
C = 	22	100
M = 	14	100


Hope that helps some?  Good luck!

Sorry for the slow response. I posted another time before I noticed 
the high L value for the K max. I then deleted that one, 'cause I 
think I was wrong. ;>)

Best,
