Let me try again. I wanted the page border to stop at page 46, as shown in the screenshot, that is, before chapter 5. The text on page 46 is the continuation of the page with the border at the top. If there are other ways to create specific page borders, they would be welcome.
Otherwise, I know that for the border of an entire book, I can directly use what PTXPrint offers, but in this case, it’s about portions of a book.
Thank you for your help.
