Allow me to disagree with that...  Blush

"Measuring the distortion
Measuring the distortion is done simply by scanning a regular pattern of vertical lines, creating horizontal path strokes and positioning anchors on the vertical lines at regular intervals:"

This should be done on which sheet? On the first or on the second (which was inverted 180º) ?

I've already done the scanners, trying to proceed but still having some difficulties in understanding the procedure.


This is what I get after adjusting and applying difference mode:

Doing the acid test and doing the calibration are totally separate things. Calibration can be done on a third scan :Smile But you can re-use the  first, upright scan.
