First of all, greetings to everyone:
Excuse my English, I know it's not very good, but I hope I can explain my problem.
I am trying to publish a book in PDF format on Amazon KDP.
I have the book written and laid out in Publisher, with the following settings for page size and margins. It is a book that only contains text, it does not contain images.
My problem is that if I create the PDF file using Word, KDP parses and loads it correctly. But if I do the same with Affinity Publisher, there is no way it will load and parse the file correctly. No matter how much I adjust the margins of the document in Publisher, KDP does not interpret the file correctly. I have tried exporting it using different PDF formats (PDF/X-1, PDF 1.7, etc.), I have also tried exporting it by including the print marks in the PDF, but I always get the same result. KDP does not interpret the file correctly.
I attach images with the page settings in Affinity Publisher, how the Affinity Publisher generated PDF looks like in Adobe Acrobat, and how it interprets the same KDP file when I upload it to your platform.
Can anyone give me any idea what the problem is and how to solve it?
Thank you very much.
