Sandy i would be interested to know how you came up with these percentages by looking at the ink separation prints?

The way I see it
% ink which gives pure white was
K 50%
C 75%
Y 80%
LK 100% (just, although probably not true pure white)

K 15%
C 20% equivqlent to 13.3% of K (50/75 X 20)
Y 25% Equivalent to 15.625% of K (50/80 x 25)
LK 35% equivalent to approximately 17.5% of K (50/100 x 35)

So the maximum black ink layed down will be equivalent to 61.5% K
And the CURVE_K= "0;0 100;100"command means that this proportion of inks is layed down linearly from 0 to 100%??

Or am I talking complete rubbish???
