To avoid the lighter ink firing at 100% you need to set the Overlap 
figure to zero (on the Gray Curve tab). Your black boost figure should 
then replicate the limit on the calibration print. I don't usually find 
this is necessary but then I'm using grayscale inks which probably have 
a darker LK.
