Your pictures appear to be backwards. This isn't helping me in my confused state.
This seems to be an amazing conundrum.
So the numbers being reported are coming from the same set of sheets i.e. they are within the 40,000 that was suggested for the BAI pattern.
But they are different positions within the sheet. So presumably if the transfer of ink was happening to the last sheet of the ream from the first sheet on the next ream then the following transfers should be happening:
Reverse imprint of AHN2867001 on the front of AHN2827999 (this assumes that the sheet containing AHN2867000 somehow vanished)
If the above is true then the other reported note should have:
Reverse imprint of AHN2882001 on the front of AHN284299
9However the note reported to have an imprint of AHN 2882001 is on AHN284299
5So what gives here?
When I look at the most recent example posted by noon it almost looks not as an ink transfer but a print of the ink (assuming we can sort out the photographs)
