Again, thank you for trying to help me.
1. Yes the original file has 3mm bleed
2. Yes to the magenta - two different files, on the magenta I got what I am trying to, the other one, no.
No, maybe it is me 😇
I suspect that I'm really not being able to explain myself correctly.
Before using Publisher, every time I export the file to PDF print, I checked the bleed and crop marks and the PDF went on like the print screen of "the right one".
Sending two old PDFs made in IDesign: so I am trying to have the crop marks touching the background.
I am very afraid that the book will be printed with white around, but if you say all it is good, so I trust
