Dave,

Do you have a starting point to print from? I mean it is easy to use
an existing paper(profile) to start with. In the Curve creation tab,
choose a paper which is close to the paper you are working with. Save
it under a different name. Then throw away the linearizing date from
the linearization tab. Create the curve (push the button!) Then in the
main interface choose the curveprofile you just made and select the
stepwedge image you want to measure from. Use the other fields exactly
the same as you want to(resolution, speed, ...) Then Print!
Let the paper dry for a while. Measure using profile maker. Throw the
textfile you create on the Linearize-data.exe file in the eye-one
folder in QTR and use the linearizing date in the just new created
(out)file and copy and paste it in the above mentioned linearization
tab. That's it. (I think)
