Getting some weird curves, read using measure tool on a X-rite eye one i0.
smoothed grey balance is checked. Took some readings with a hand held and they are close to what you would expect.
These are a little odd compared to what we normally expect for a well-linearized printer or press. IDEALink Curve should be able to pull these curves into line in one or two passes. Have you applied these curves to your RIP yet?
