August 28 A sad day as I have decided to no longer allow Hermitian to submit comments on this blog as he has now, several times accused me of behavior for which he has no evidence (hinting that I may be the forger, work for Obama, that I withhold data or manipulate data and other non sequiturs). I feel saddened because, despite his short comings, he did serve a useful purpose. I wish him well and will continue to address issues he raises, to help him understand better why the Xerox workflow stands unassailed. Thank you Hermitian for your efforts to debunk the work flow, helping further strengthen it.
From the FreeRepublic we receive some good feedback from a poster named Butterdezilion.
Butterdezilion: If the Xerox machine is substituting exact replicas every time a certain “blob” (such as a box) appears, then that should happen with every box, every letter, etc. If the Xerox is switching 6’s for 8’s then where are those numbers switched around in the White House PDF?
A good question but as I have shown and found out, the Mixed Raster Compression is all but exact as it appears to be extremely sensitive to small variations. I have seen examples with anywhere from 4 to 17 foreground images. The same for JBIG2, it is based on how similar the two blobs, such as a box are, and in the samples I have, I have found JBIG2 to fail to capture the boxes, but it does capture other letters.
