OCR badly indicates 0, O & q is there a way to avoid this?

I'm scanning ID record in PDF in a database, for example:

1-5Y-1490
1 MSPQK4
1 M7S9HO

OCR does not seem to differentiate between 0, O & Q.

Is there a way to avoid this?

Any advice would be greatly appreciated.

Thank you very much!

Your significant variables are associated with the study of the source and the real parameters used to configure the scan activity.
Old paper source usually does not above provide a contrast between the print and the paper. Character recognition impacts.
Most "clutter" (lines, curves and other) more character recognition.
So while the software can tweak a smooth is what efficiency will always be founded by the source document.
(& look well is not the same as something fresh out of the printer with clean and sharp black text on comes out sheets of white paper envelope)

If OCR "recognizes" bitmap "O" as "0", you will have not a 'suspect' - the character has to be '' recognized '' huh.
("m" is recognized as "n ~ '-two valid characters and not a" suspect "" ")

By using indexable or searchable Image (exact) what you get is what you got.
"ClearScan" using cards little recognized characters are replaced by a font having visible glyphs.
If manual 'cleansing' of the characters is possible. Slow, tedious - but possible.
(PDF tolerates a "touch-ups" but not processing as 'change').

About "ClearScan" - it was renamed in Acrobat DC.

--| If you use Acrobat Pro, Clearscan has been renamed to "editable text and images.
'Editable text and images' are not so available for Acrobat Standard.

--|  ClearScan has been upgraded to 'Images and editable text.
Now it uses heuristics to determine the original font that was used in the original document.
This feature is now also available as a part of the edition.
So now you can edit your scanned documents too with tool 'Edit PDF'.

--|  There will be no difference in the appearance of the text that already exists.
The relevant part is on the attribution of the name for the created fonts.
Fonts were created in ClearScan also, but they were named something like FDxxxxx.
Now, the appearance would be exactly the same as Clearscan but it will make the font that was used in the original document
and assign it a name accordingly.
In addition to this, if you want to add a new text, since we figured out the police
We will try to match the appearance of a new text with the existing text.
It wasn't there to ClearScan.
Therefore, there is an upgrade with additional features without compromising the aspect.

--|  There is no functional change in the output options. However, we continue to improve our features in terms of performance.
