OCR without down sampling images and letters

[Eugene98BC]

First picture is original PDF

Second picture is a result of Enhance Scanned PDF

Thrid picture is setting about Enhance Scanned PDF

Hello, first thank you for reading my post.

I did "Enhance Scanned PDF" with no Optimization, only Recognize Text(Editable Text and Images)

After that, in the second picture, a letter("x") and some axis line("x - east and y north") image are going to poor images and letter in comparison with the first picture(original)

I want to not changing letter("x") image or letter("x") also scanned OCR like letter("y")

How can it possible?

Hello @Eugene98BC 

I hope you're doing well. I'm sorry to hear that you're experiencing an issue with your PDF files.

To better assist you, could you please clarify whether this problem is specific to a particular PDF file or if it's occurring with all PDFs? It might be helpful to test with a different PDF file to see if the issue persists. If the file is located on a shared network or drive, I recommend downloading it to your local computer and then attempting to open it again.

Regarding the version of Acrobat DC you're using, it's essential to ensure you have the most recent version installed, which is 23.03.20284. You can verify your version by going to Help > About Acrobat. If you find that your version is not up-to-date, you can check for updates by going to Help > Check for updates. After updating, make sure to reboot your computer for the changes to take effect.

In addition, I suggest taking a look at the solution marked as correct in a similar discussion on the Adobe Community forums. The discussion can be found at this link: https://community.adobe.com/t5/acrobat-discussions/loss-of-quality-when-i-recognize-text-in-my-file/.... This might provide some insights or steps to resolve your issue.

Please give these suggestions a try, and let us know how it goes.

Regards

Amal
