Bill:
I will only tell you my opinion, based upon experience.
While I am glad that your system is running well, I would do it differently.
I would use 300 dpi and G4 compression, which will counteract some of the
file size growth. I would not go below 200 dpi in any case. There is no
question that overall, 300 is a better choice for recognition, particularly
if you move to semi-structured forms or have dense layouts. What error rate
are you getting with 200? Might there be specific forms where 300 could
make a difference in overall performance?
It is increasingly rare to hear people talk about storage as an issue, based
upon the recent pricing - $100 for 250GB magnetic. Of course, I don't know
how many images you are collecting in your system.
While the film looks good today, I have concerns about how it would look
over time -- they may be unfounded. The extra resolution can't hurt.

>>Digital Imaging Guidelines available online<<
Greetings all,
Just a quick question. Most of the guidelines I have read suggest scanning
and storing documents at 300 dpi. Just a thought, but I find this a bit
excessive unless there is a good chance that the documents will be OCR'd in
the future.
We are revising our standard to a standard 200 dpi with even lower dpi
permitted on high quality text documents. Bandwidth and storage
considerations are two reasons for the move. Quality of the images is still
very sufficient to meet any evidentiary requirements. Our forms processing
solution is based on the TIFF G3 standard of 200 dpi and does an outstanding
job of OCR, ICR, OBR and OMR at the 200 dpi range so not sure I even can
justify the 300 dpi setting for OCR purposes. We write images from our ECM
to a Kodak DAW at both 200 and 300 dpi without noticing a difference.
Any discussion?
