Hi David,
I think the penny has dropped!
<-----Original Message----->
100% GCR setting, Black generation starting at zero at 45 degree
angle upto the point where colour is required to enrich the black. At
that point, dip the black to add colour.
Using UCA would start the UCA toe lower than your first diagram (never
heard of a UCA toe control... but I guess it would be possible to build
that feature into a program, the interaction of all these functionsb
becomes mind bogglingly complex, however).
.......Yeh! I'm thankful that I never went down the route of programming
for a career. I never fancied wearing anoraks :->
Your second diagram is indeed the alternative I am describing; though
you don't have corners in a spline-defined curve, so the start of the
dip would be a curve instead of an angle, and the end could curve right
up to 100% (or fall short of it if you like) instead of easing back to
the original ramp with a recurve, if you prefer. Whether this
configuration will give you good results in print is a different
question than how you would generate this seperation; I was giving you
what you were asking for, without really knowing if its a reasonable
seperation for your usage.

Cheers!
