Hi. I am scanning several individual pages of books on a Konica Minolta Bizhub 601 as 600 dpi multi-page PDF files. These files are then being uploaded to the Internet Archive (www.archive.org) website. Unfortunately I have discovered that these files have a hidden text layer that I am unable to find or know how to remove. Essentially, the files should be upload as PDF images. I have 44 files already scanned and am hoping that I will not have to redo them all. Can anyone advise as to how to remove a text layer so that each file is uploaded as PDF images? Can this be done in Preflight? Thank you in advance for any help and support.
