Thank you for the link. I patched and recompiled the epkowa backend, but
the result is still not perfect. While there are clearly less coloured
stripes/lines, and the photograph scanned is also easily discernible,
fine vertical coloured lines running through the whole image still
remain. It reminds me the time I had a Microtek Phantom 636cx and the
backend lacked a good shading correction. Maybe this is also a
less-than-perfect correction for the sensitivity unevenness of the
individual pixels on the CCD?
