No problem here.

The KA655 TM was done at 600dpi ... the source,
however, was a none-too-good photocopy.

Remember that Acrobat will display however
you tell it to and fit-to-page on a 17"
monitor looks quite different to the same
on a 19" or 21" monitor. Try fit-to-width
and see if that helps.

I suspect that if they mandated a standard
then they might put off people who might
otherwise contribute (and I still say
that any scan is always better than no scan!).

The scans just need to be good enough to
be able to be OCRd perfectly 10 years from
now (once someone gets around to writing
OCR software that works almost perfectly
rather than the current crop which seems
to fail most of the time).
