Question

OCR of white text on dark background is not consistent

I saw this asked before in the forum (sometime 2011), and the response was that as long as there is significant contrast between text color and background color, Acrobat can OCR white on dark or dark on white.

This is not consistent though. I already tried to OCR an image with both white text on black background, and black text on white background (on the same image).

The black text on white were recognized, but the white on black were not.

I'm trying to write a script or action in Acrobat to automate OCR and save to text file when opening image/PDF. But this limitation is an issue.

Any idea if this will be fixed?

I'm using Adobe Acrobat XI Pro for Mac (11.0.19).

    Hi there

     

    Hope you are doing well. If you are still experiencing this issue, please update the application to the latest version 24.05.2039X from the help menu > check for updates and reboot the computer once and see if that works.

    I continue to have the same problem but with windows 10 version 1903 on a Dell Intel Core i7-2670QM and 8GB.

    The software runs without other issues but OCR will not convert white image text to editable text.

    Adobe Acrobat Pro DC version 2019.021.20061

     

    Any solutions?

    Hi

    I had the same problem. White type on a green solid was changing to transparent / disappearing in my pdf. In Indesign it was fine. And in the previous pdfs it was fine.

    However, once I tried to make the pdf accessible, Acrobat was rendering the type as not having enough contrast and trying to fix it (I guess). It only worked when I selected Recognize Text Using OCR > Output > Editable Text and Images. Then it kept my white type on a solid.

    That only took 2 days to figure out.

    Good luck.
