The perforation is not measured or measured incorrectly.

Possible causes are:

The stamp was scanned with a too low resolution. Set your scanner software to a resolution not less than 300dpi. For best results, use a resolution of 600dpi.

In manual mode, the stamp has to be rotated and cut before measuring.

In automatic mode, the stamp was not rotated or cut correctly. See the next section.

The stamp is not rotated or cut correctly.

There are bright spots or edges in the image background. Make sure that the background of the stamp is absolutely free of paper residues and other particles. If necessary, clean the glass pane of your scanner. Make sure that the whole picture background is black and that no parts of other stamps are in the picture!

The brightness and/or contrast of the image is too low. Try to scan the stamp with a higher brightness and/or a higher contrast.
