After being without one for several months (and prior to buying Acrobat Pro ver. 9 for a Windows 64-bit machine), I just got a new scanner a few days ago. So far, the scanner has been doing a great job but I've come across some very frustrating problems with Acrobat:

1. It took me two days to discover that convert text and graphics no longer exists in ver. 9 and has been very well hidden, underneath far too many menus, to find that it has been replaced by "ClearScan." This feature is barely mentioned in Acrobat's help files, not mentioned in the greatly overpriced Acrobat 9 "Classroom in a Book" and, after spending many hours trying to figure out why the characters in my scanned documents looked like they had been built with Legos, finally came across this forum which also have very limited information.

2. Once I came across ClearScan and got it to work, my documents now look quite a bit better but, once again, that's not the end of the problems as touchup text no longer seems to work :(

3. Just to see what is going on, I exported a scanned .pdf to a .rtf file and, not surprisingly, found quite a few minor errors. Becuase I can't get touchup text to work, what do I do now?

4. When I looked at "examine document" a few works that clearscan did not convert show up as "hidden text" and I can't figure out how to change that to visible text.

So, here are my questions:

1. What is the optimal setting to scan written materials and convert with OCR.
2. Is there a bug with touchup text so that it is not possible to correct errors?
3. How do I convert hidden text to visible text?

Thanks.

ClearScan (new technology) was previously referred to as PDF Formatted Text & Graphics in Acrobat 6 -8. The file conversion is made to a PDF with scalable text and graphics and thus can be edited and altered. To edit the text using the Touchup tool you'll need to change the font from the custom fonts to a font that is available on your computer.In regards to an optimal setting, for the Clearscan to work an input resolution of 72 dpi or higher is required, and input resolution higher than 600 dpi is downsampled to 600 dpi or lower. If you're converting black-and-white pages try scanning at 300 dpi for proper conversion of text.

Thanks for your response. Can you tell me where I go, in Acrobat 9, to change the font?

Thanks!

Selecting the TouchUp Text Tool ought to result in Acrobat loading system fonts.

Thanks for the suggestion. Unfortunately, I still can't edit text. Acrobat says "loading system fonts" but then nothing happens. Trying to edit text then results in an error message that states,

"All or part of the selection has no available system font. You cannot add or delete text using the currently selected font."

I also get the error message,

"Accumulated text within the attempted selection area is rotated other than horizontal or vertical. TouchUp cannot create a text selection."

After spending a lot more time searching for answers to the problems, I came across two threads at:

http://www.adobeforums.com/webx?14@@.59b5db5f/4

and

http://objectmix.com/adobe-acrobat/718940-acrobat-9-ocr-ocr-suspects.php

At this point, I'm beginning to think that Acrobat 9 (with "ClearScan") may be one step forward and two steps backwards. Any other ideas?

I've just found an issue that may, or may not be related to the problems I'm having. As I continue to play with settings to get the best possible output (which ClearScan seems to do very well), it (ClearScan) also seems to mess up the underlying OCR material - which appears to be why the TouchUp Text Tool doesn't work well.

As an experiment, I thought I'd see what happens when I tried to get Acrobat to "Read Out Loud" (while I need easy-to-read documents for me) I've got a friend who is visually handicapped and the pdf. documents I scan must look nice (for me) but also must be fully accessible for him. This is where I've come across a MAJOR problem - after using ClearScan on a document, it can no longer be read using "Read-out-loud."

I've now examined several documents and this seems to be a problem for all of them. As a result, fully-sighted people (like me) are benefited from ClearScan but visually handicapped folks (who must rely on "Read-out-loud" are then denied access to the same document. Intestingly, ClearScan helps those who do have limited visual abilities.

Another matter is that, when converting a scanned document to MS Word (2007) from Acrobat, ClearScan works better than using the original scan. Hope this helps someone.

You can fix it in Photoshop (I did it in CS4, it opened the pdf and saved it in pdf) Or you can change it to jpg in an earlier version.

These forums are now Read Only. If you have an Acrobat question, ask questions and get help from one of our experts.
