I think the AP LFCOLB is a print-washed scan of the WH LFCOLB (or a version of it). That is the third time I have said that to you.
Further - the absence of issues in the AP pdf does not explain away those issues in the WH pdf.
Is that clear enough for you?
I have no idea what you mean by a "print-washed scan."
You can't scan a low-quality document, and get a high-quality one. You can't print out the PDF, scan it, and get the AP document.
Therefore, you've GOT to have a MUCH higher quality document than the PDF.
And since you indisputably and unavoidably have this much higher-quality document than the PDF, there is no reason whatsoever for anybody to go to all the effort to hand-construct layers of forgery in some much-lower-quality PDF.
