Text is only searchable within Edit PDF Tool when there is a background image
I have a pdf file where the text is only searchable when I am using the Edit PDF tool. The text is fully selectable and the fonts are embedded in the file. However outside of the when I'm in the edit tool, I cannot search for any text.
I've found that this problem only seems to occur when there is an image included in the pdf. If I recreate the same file without the background image I can search the text.
Any ideas on how to resolve this problem? I need to retain the image in the final pdf. I am using the adobe acrobat printer to create the pdf.
