Yes, deliberately. It adds noise and slight rotation, so keep the clean original.
The visible page becomes an image. Any existing text layer may be lost, so re-run OCR if you need it.
For visual consistency in an archive, yes. Never use it to imply a digital file is an original signed paper document.
These tools handle one document at a time. When the job is thousands of files, Greenbooks handles document digitization as a managed service, including bulk scanning, OCR and metadata capture, with the output loaded into DocuVenta DMS. Talk to us about volume work.
