I did do the reduced modification of LC=LM=20 and it is about perfect, maybe slightly
blue and a bit dark compared to the Epson driver.
Will next reduce LK a bit as you earlier suggested. If that isn't perfect, will try the mods
you suggest below. I suspect that a bit less LK will make it great though cuz it is so close.
Interesting how ones opinion can change: I had thought of the Epson driver print as very
cold; now it looks a bit warm compared to LC=LM=20 with the "20" print being cold
neutral.
or is the Epson cold neutral and the "20" print a bit blue? sigh...
will take a bit of relooking as time passes to decide. Both nice though ("to date")
Thanks

You can try to change GRAY_GAMMA (midtones), GRAY_SHADOW (shadows), and
GRAY_HIGHLIGHT (highlights). Higher values make that part of the curve
brighter, lower values darker. Gamma will usually stay between 1 and 2
somewhere while the other two can be anything from 0 to 300 or possibly
even more.
I honestly don't know how well it works to tweak these values with
linearization in place. You're supposed to tweak them first and do the
linearization as a last step. You can try and see how it works. If the
results are horrible switch off linearization and try again. You can
actually pretty good curves without linearizing. I've made a couple of
curves which I haven't bothered to linearize simply because I already
get great prints from them just with the adjustments mentioned above.

Hi John and Dan,
I went with the lighter modification below "30 a s a start. Installed it and tested. The
print
comes out a bit blue which is great,
because I can easily blend it with the warm one to get just what I want. And also
because I
just learned a ton. :)
It did make the print overall too dark though---as might be expected. Is there an
easy
number to change for that? or just reduce the ink limit?
as a start will re edit the curve to an intermediate effect, maybe LC=20 or 25.
Likewise for
LM.
Bottom line is that blue is good, allows flexibility, and I am on my way.
