Wrong bleed in Publisher?

[Gianni Becattini]

I am very sorry to bother you so much, but I am delivering my work and it seems impossible to finish it. I know I owe a dinner to many of you....😀

The problem this evening is that the page bleed seems to be wrong. I get the bleed of the left page on the right page, and the bleed of the right page on the left page. If you look at the attached file, you can understand immediately the problem. Am I doing something wrong or is it a software bug?

Thank you very much

As far as I know, this is what we are supposed to see.

Don't mind too much about that.

This glitch seems to me to be almost always a false problem, because it only happens in the center of a spread, thus there are two possibilities:

1. Your file will be printed on 'folded sheet' (sorry for my poor language) so there will be some imposition and the two pages will always be placed (and printed) just aside another one by the software, with no gutter nor any cut between. This means there is no bleed needed in this place.
   (Printing software will manage this for you without any problem.)
2. Your file will be printed page per page, on single sheets of paper, then they will be trimmed to have full page printing. Bleed could then seem useful but luckily, because these bizarre bleeds are in the middle of the spread, the pages will most probably be stitched or glued and a possible error of trimming will then be hidden in the ply. 
   — The only situation where I see that could be a problem is for single pages bound with a spiral wire, or the like. In that case, because you will see the two complete pages open flat, any error of trimming will show the wrong page border, as in your PDF.
   But beside this special case, I don't see any problem to this quite surprising behaviour. 

I don't see any reason why Affinity does it like that; in my opinion, there could just be no bleed at all there…

Actually the inner bleed shows the inner edge of the opposite page, not the bleed of the opposite page. – This is what you would expect if both pages would get printed on a large sheet ... just like on the layout you place the image bounding box at the spine without bleed + show the contents of the other page right next to it.

I understand and fully agree. I also, continuing to think, was arriving at the same conclusions. Even if I can understand the printer problem.

Knowing that Indesign and QXP do the same is very important.

Thanks!

"Actually" there is none: Either the printer's imposition software will handle the inner bleed of your delivered PDF as required or they may demand a PDF without inner bleed.

The usefulness of an inner bleed depends on the type of binding (thread, glue, spiral) and the cut print sheet / page size. For thread stitching the printer's software might rather avoid to print the inner bleed. For glue and especially for spiral binding the inner bleed may be wanted if the layout has an image or coloured background across two pages / the spine of a spread, while an inner bleed may disturb if one page of a spread has colour up to the spine while its opposite page does not. In the latter case precise cutting is required, regardless of printing the inner bleed or not.
