The following image is a composite created by scanning the WH LFBC using Xerox WorkCentre 7655 upside down using the automatic feeder. The resulting file was opened in Preview, the image rotated 180 degrees and printed to PDF. The resulting PDF was opened in preview, the layers unlocked and moved to the side. In addition, a close up of the signature was ‘blown up’ to show how the background layer, not surprisingly, has filled in some of the white that resulted from the separation of the background and foreground layers.
Note how for example the signature block is fully separated.
