A prompt on the upper-right corner appears showing you the recognized OCR language. To change the language, click Settings in the prompt or in the right pane. For more information about the various options, see Options for editing scanned documents below. Click the text element you want to edit and start typing.

For more information, see Enable or disable auto-OCR for scanned documents. Use the settings to change OCR language, choose whether to use system fonts, and make all pages editable at one go. In the right pane, click Settings under Scanned Documents. The dialog box shows the following three settings:.
This tutorial shows you how to work with the Scan and Optimize features in Acrobat 9. See what the all-new Acrobat DC can do for you. Document scanning and OCR workflows sometimes include as much art as they do applying processes and commands. Often older source documents, maps and artwork are in poor condition. In addition to being physically fragile, the documents may have lost contrast, color definition and clarity.
You can improve scan quality in several ways, depending on your intended use for the material. On the other hand, contrast is the most important feature for content you intend to capture using OCR.
Acrobat 9 offers a feature to scan content directly to a PDF file, using a number of settings and scan options. Click the Create PDF task button to open the menu, choose From Scanner and then select a text or image preset according to your document.
The Configure Presets dialog box opens. Click From Scanner to open the dialog box directly. The default option, roughly at the center of the slider, is appropriate for basic scanning and OCR. Figure 2: Choose an optimization level according the desired quality versus file size.
Click the Options button circled in Figure 2 to open the Optimization Options dialog box where you set compression and filter settings Figure 3. Acrobat offers several optimizing filters to adjust or correct your scan results; before and after examples are shown for each filter:. Use Background Removal for grayscale and color pages to brighten nearly white areas to appear white, resulting in clearer scans Figure 5.
The default is Low; you can also choose Medium and High options. Figure 5: Correct a common fault by changing the darkened background left to white right. Remove the black edges sometimes seen on scanned pages using the Edge Shadow Removal filter Figure 6. It might still crash occasionally, but at least I did not have to repeat what had already been done successfully. Knitting the broken files together after successful OCR processing is really quite trivial, done in seconds, not a hardship.
But how nice it would be if the fix applied to Version 9 would also be applied to version 8. As a volunteer, I can't afford version 9, and my version 8.
When the next big group of similar PDF files emerge, I won't waste so much time experimenting. I'll just repeat this process from the beginning. Regards, and thank you for thinking of me, appreciated. Terry Smythe. What kind of fix do you mean Adobe has applied to AA9?
Since installing the boxed version, Adobe's Update application never found any updates for AA9 Acrobat 9 crashes on OCR. Reply to author. Report message as abuse. Show original message.

Bill VT. The basic problem is that the png file is a X resolution. The minimum is dpi. I tried it in AA5 and it warned of an invalid resolution.
I switched it to 2X the resolution. At that the OCR ran, but the only conversion was on the page number. I have no idea why AA9 would have crashed, but it is likely related to the page resolution. Every other page in these documents are the same dpi so I don't think that is the issue.
Not sure this is right place for this question, but Is there a "one-step" way to highlight all the occurences of a particular word in an OCR'd pdf? I currently find the 1st occurrence and highlight it, then find the next occurrence and highlight it, then find the next occurrence and highlight it, and so on Mark, This thread relates to crashes with OCR. I have sent the email with the attachment.
Thanks for your help! Olga Satchouk, Acrobat QE. Thank you. I hope it is released soon as I have 6 more cases where it crashes during OCR.
Perhaps they are all related to this common cause that you have already fixed. Yes, it looks like the same problem on all pages caused crash in Acrobat 9. All pages came out just fine after OCR with 9.
