I'm using Automator in combination with Abbys Finereader to watch a Folder for new scanned PDF documents. The Finereader OCRs the Document and exports it to a new PDF in the same Folder. For a month now I've used the export Setting "text over page image". The User Guides explanation of this setting is:
This option saves the background and pictures of the original document and places the recognized text over them. Usually, a PDF file saved using this option requires more disk space than a file that has been saved with the Text and pictures only option enabled. The resulting PDF document is fully searchable. In some cases, the appearance of the resulting document may slightly differ from the original.
The problem is that some of the PDFs that have been scanned and "OCRed" have many wrong characters in it but I just found out about this failure.
Is it in any way possible to "roll back" to the Version without the OCR? I tried to export the PDF as an TIFF File, but in there are also the wrong characters...
