not possible, retake image at lower
exposure. See exposure guidelines
Section 5.1.

images or shadows.
Imaging plate was not
completely erased.
Increase the amount of time that is used
to erase plates. Alternatively, increase the
intensity of the light source. To te st if an
imaging plate is completely erased,
simply mount an erased plate on a
carousel and scan it. If no image is
obtained, your procedure is effective at
completely erasing imaging plates.
