QTR-Quadtone RIP

The agony and the ecstacy . . .

Best prints ever, sans adjustment, but this time, the 0%K, white areas
of the image are being covered with about a 1-2% K when I use the
QTR-ICC profiles. Anyone have an idea if I'm doing something wrong
with profile creation or is this maybe a bug?  Doesn't change either
if I try to use a different rendering intent. Also, when I don't use
the profiles, and just the QTR curves, the white seems to be mapping
correctly, ie: no ink.

Any help would be greatly appreciated.
