Newbie: wondering why a fairly crisp document has such low accuracy

[Stephen Boesch]

I printed out the "Welcome" page on my HP laserjet printer and scanned it in using .png .  The quality is quite good. So I had been  anticipating maybe 85%+ accuracy on the tesseract-OCR. I did not even bother to tally carefullly - but by eyeballing it seems about  50%.    I had used all default settings.

Some of the consistent errors:

W -> H

in -> m

li -> h

b -> t)

ll -> H

So is this just "the way things are" in OCR land?  Or am I missing some fundamental settings here - to get some reasonable usefulness?

thanks

With English you should probably get close to 99% accuracy.

Is your png at 300 dpi?

Which version of tesseract did you use?

Which traineddata?
