Hello everyone, first time poster
I recently received a huge pile of book scans in the form of big, complex, pictures-rich pdfs with background textures (parchment/old paper), very difficult to work with. The task I have been given is that I am supposed to add a layer of invisible, searchable text to each of these pdfs, but without touching or loosing any quality in the underlaying document. I have been struggling with the settings of my FineReader 10 for a few hours, searching for existing answers, but no luck so far, the pdfs I end up with are either degraded, or with the text inserted visually in the document.
Is there anything I can do knowing that :
Basically, I want to just make the pdfs searchable without touching the actual content, is that even possible ? Thanks for your time
