Which printer and inkset are you using Johnny?  Try setting the
precise light slider to -10 or so.  The gentleman reviewing the
package at NorthernLight had similar problems and it may be related to
metamerism of your inkset.

Anyhow his review can be found at:

The Epson R1800 seems to profile dead on but the inkset has very low
metamerism.

Hope that helps
