My Dear Sir,
Please help me as this thing has taken lot of my time.
I have a need to OCR the documents. I have tried many ways to do it, however it seems that when I try to OCR an existing PDF it doesn’t give me the desired results.
I took one document of 12 pages & scanned it in TIFF & PDF. When I OCR’D it the TIFF version was way more accurate than PDF. The PDF was made using Acrobat & I scanned it directly in Acrobat Professional 8.1
We are dealing with certain Legal Documents & it is the need that the PDF should be made from the Original Paper, but if we can’t OCR the PDF after it is made it becomes impossible to work. Also the size of TIFF is so big that it takes too long to go over the internet.
Also I would highly appreciate if you could kindly tell me what should be the correct resolutions to Scan a document for getting the best results to OCR?
Best,
Sahil
First, I'll start with the last question you asked. The resolution for a scan to OCR should be 200 ppi and the document should be grayscale (for best accuracy). However, this will create a fairly large file (even as a PDF). To reduce size, you might try the text or black and white only option on the scanner at a higher resolution (anywhere from 300 ppi on up).
As for accuracy, be sure to use the setting, Searchable Image (Exact) to get a document that looks exactly like the original document, but can be searched. The OCR may fail on some words in the document (depending on the original paper you scanned), but can always be read by a human.
