Someone contacted me not too long ago through my website, the Online Canadian Paper Money Museum with a question about the note featured in the attached photo.
I have no idea how this would have been created. It is difficult to tell for sure which layer (the intaglio or the "plaid") was printed first, even with a magnifying glass. The prefix is AGG, so it has an engraved back as opposed to a lithographed back.
I am not aware of anything within the normal printing process that could possibly have produced what I am seeing.
Does anyone here have any thoughts or ideas?
