Default OT microfiche

3600 dpi in jpeg ? that trashes the data in compression -

or in TIFF that maintains high res.

That might be the issue - and are you sure it is 3600 in B&W or 3600 in color and you get B&W.
You might do a single page at a time. Put the res in the smaller box. You would have to have
done that or the file size would be a monster...

What you need is back lighting - through frosted milk glass.

You can get some of that at a glass company. The scanner reflects off the surface
with the internal lamp - hope you have a way to turn it off. I do on my HP -
I plug in the Slide / film unit and it is a lamp. Turns off the internal reflection
lamp.



Well, you've just reinvented the transparency scanner. But lighting is
only part of it, resolution still isn't quite there. The example I
posted at 3600 DPI is mostly readable but hardly clear. Optical
resolution is the only thing that'll get you there.
