Digital BW, The Print

I had some trouble with printing some smooth clouds in a print on the 3000
with the VM-S neutral curve.  With the 21-step test file that has 1%
increments for the top (and bottom) 5% range, I found that the spacing was
not even.  (0% - 5% = .04, .05, .05, .06, .07, .09)  I have noticed and
fixed this with a few of the curves out there, but not all.  With
adjustments to the 3000's curves I was able to get a perfect spacing of 0.4
(paper white), .05, .06, .07, .08, and .09.  This made a significant
difference in the final print highlight smoothness.

If you have blotchy highlights with vm curves, let me know which curves are
the problems, and I'll just apply the same remedy to them that worked for
me, and we'll see if that makes a difference.

But how about the way PS7 treats the greyscale conversion from gamma 
2.2 to sRGB vs PS6...I mentioned before that it converts differently. 
Using Adobe98 lessens the deviance somewhat, but most of your VM 
curves are based on sRGB conversion. I had posterization in a very 
dark print due to the PS7 change. If you do a histogram of a dark 
print file converted to sRGB in both PS7 and PS6 you will see the 
slight differences in mean, SD, and median.
