Hi Ian,
I think you are right and you are wrong.
The calibration would correct effect of a certain scanner printer combination.
However, it would be a general correction not only valid for a printed and
then rescanned image, which would indeed make not very much sense, but for any
image. The reason why you have to use a scanned and printed image for the
calibration is that you need a reference for the calibration to take place.
Regards,
Andree
