Typical file is 700 pages, comprised of 8 groups of PDFs that are combined into a single document.
It may be related to default setting of other users who have redlined the file, but does not seem to occur if I am the only person redacting information. Normally files are fully redlined and reviewed before redactions are applied. Occasionally redactions are applied, then redlining continues. Testing this on a small file did not seem to make any difference
A pattern of redactions seems to repeat over areas that were not marked for redaction - very obvious when watching pages coming out of the printer. These "redacted" area still show text faintly through the black. These were NOT intentionally repeated.
