I just opened the PDF file and holy cr@p I think you are right.
That white ghosting is around all the letters.
Look at a letter “O” or “C” and you can’t see the security paper.
This looks like chunks of text pasted on the security paper. The text chunks cover the security paper.
Back in post 336 I said
That looks like unsharp masking was applied to the image. If you look at the parts of the image which are less sharp to begin with, especially the document number 61 10641, you'll see less of an artifact. Many digital cameras and scanners do this type of sharpening automatically unless you turn it off.I stick by it. Another indication of unsharp masking is the last 1 in the "Apr 25 2011" stamp. The right edge of the one appears to have fallen right on the pixel so it is half dark and there is no boost from the dark left part of the one, to the half dark right pixel to the background. That's one of the problem of digital unsharp masking algorithms that it can't handle a pixel split evenly between a dark section and a light one.
The centers of the letters O, C and U get hit with an unsharp mask from both sides which tends to wipe out the background.
What do you make of the “Dunham” signature?
The “D” in Dunham looks like an image right on the paper itself, while the “unham” looks as though someone went into to photoshop and darkened each letter on a pixel basis. I mean you get the real crisp edges in the “unham”, but the “D” has the grayish squares that you normally see in a pixellated image.
