Thank You!! A huge help. Do you know who "determined" that those were the correct fold placements? Was that you? Do you know if there is an exact image of this document without the red printing/imaging?
Yeah that red document is nothing official. It was something I threw together as part of a discussion on one of the threads. It was made using the colour image of the 340 that I have also posted here. There are fold marks on the 340 but unfortunately it's not easy to reliably assess where they are. The colour image of the 340 is, I believe, a scan from a photograph and as such was most likely taken from under glass and possibly vacuum to hold it flat. That, combined with the fact that the image isn't hi-res as we would understand it, means we're guessing at some of it if they were fold marks. Some most likely are so I think those are the ones marked on the red image and decided on through consensus.
