There were two attempts to forge the COLB:-
1/ A simple Photoshop job that only exists as a computer screen/ website image.
2/ A physical composite of green security paper and a high temperature resistant plastive film adhesive on one side and laser printed text on the other.
Why?
Because the ALIGNMENT of the fine pattern on the green security paper IMAGE of a COLB with the text on that IMAGE happened first.
To match it, the second forgery of a physical COLB had to maintain that pattern/text alignment almost exactly.
Just loading a tray of Security paper into a laser printer and printing the text from a photoshop program does not mean the alignment will match over the whole page.
Doing a total Photoshop with black text on a green background and printing it on white paper will produce something that may look OK from some angles but when folded won't look like a real COLB.
But if they had access to the security paper, why would they do the "simple Photoshop job" first? Why not just print a fake COLB to begin with?
For me, a conspiracy theory has to make at least as much sense as the one it's supposed to replace. This one doesn't.
