Took quite a bit of time to find out what was causing the lines..
We edit abstracts, we have a records system that has stored scans of court documents in .tif format. To add these to an abstract we need to print them off from that program to PDF files, many of these scans are not straight so I have been using the deskew feature in "Scan and OCR" in the "Optimize Scanned Pages". I turn off all but the "Descreen" in "FIlters" So no adaptive compression, no recognize text, background removal, or text sharpening.
This works well, however using this tool on pages that have been printed with the Adobe Print to PDF printer that is installed with Adobe Acrobate Standard 2020, random lines are added to the page, when complete. No lines are added from pages that have been scanned in, only pages that have been printed with the adobe print to PDF printer.
Why is this happening and what can I do to prevent it? I have tried turning off font smoothing and other settings on the printer driver, with no success.
