OCRing reduces quality of document

Recommended Posts

MB1

I have had a number of instances where OCRing the document distorts the visible text on the document--e.g. makes it fuzzy, changes the spacing.  This is unacceptable.  Any way to fix?  I want the look of the document to stay exactly the same after OCR.  Based on reading posts in this forum I am not the only one having this issue.  I have used Nitro for many years, but I do not recall having this issue until fairly recently.

Hello @MB1,

Thank you for reaching out to us through our Community Forums!

Before running OCR, kindly go to Advanced and use higher quality settings:

Thanks for choosing Nitro and I hope this helps!

thanks, but I don't understand this response.  I currently have my OCR "quality" selection on this options screen set to "High(slow)".  Are you saying that if I change to medium the appearance of the page will not be altered during the OCR process?  

Also, I assume reducing the setting from high to medium will reduce the OCR quality?

Hello @MB1,

Thank you for letting me know you are already using High under OCR settings.

In order for me to further assist you with your concern, could you please send me a private message and provide a sample file (with sensitive information extracted) so I can replicate it on my end?

To send me the sample file, hover your mouse on top of my name 'AllainU' and select 'Message'.

Also, what build of Nitro Pro are you working with? You can find this out by clicking on 'About Nitro Pro' under the Help tab (format is 12.X.X.X, e.g. 12.0.0.112) or you can go to Control Panel > Programs and Features.

Thank you very much in advance and I am looking forward to hearing back from you.

I am using version 12.0.0.108.  I do not have a sample file with non-confidential information that I can send.  More importantly, my concern is what will happen to future documents, not documents already processed.  I think the question is simple and of general interest:  does using the "medium" OCR setting prevent distorting of the page image?  Acrobat has an OCR setting that preserves the visible document image during the OCR process.  Is the "Medium" OCR setting in Nitro analogous?  

I deal with legal documents and need to keep the viewable PDF image exactly the same after OCR.  Based on my own experience and reading other forum posts the image is often not preserved in Nitro. I am trying to understand why and how I can prevent image distortion.
