QTR-Quadtone RIP

Hello,

I am very new to QTR.
There are a few questions that are stopping me right now.

With the latest version of Spyder3Print (-> spectro measurements) QTR profiling is supported. However, I could not find any documentation on this subject. The spyder guide only mentions this feature.

The options in Spyder3Print are linearization and createicc.
Would somebody so kind and explain the steps?

Another problem I am facing is the recommended 21 x 4 step wedge from the Eye-One folder seems to be too small for the Sypder spectrometer.
Is it possible to enlarge the wedge without affecting the measurement?

Thank you in advance.

Regards
