* The delta E isn't going to tell you a thing. You're best bet would
probably be to take a look at the L* axis at each step and plot them out.

How about this data?
Contone Print Screened Print
C10% L = 95.0 C10% L = 91.1
C20% L = 91.2 C10% L = 85.0
C30% L = 87.0 C10% L = 79.4
C40% L = 83.2 C10% L = 74.0
C50% L = 78.1 C10% L = 69.6
C60% L = 74.2 C10% L = 64.9
C70% L = 69.9 C10% L = 60.8
C80% L = 65.5 C10% L = 57.2
c90% L = 58.9 C10% L = 53.5
C100% L = 50.5 C10% L = 50.7
I would repeat this for each of the other channels but I do not know how to
translate this into a 10 point curve. I am trying to get the Screened Print
(1-bit tiffs) to print properly at 2880x1440dpi. Right now, the color is
good, but the print is much too dark.
