Hello all.
I designed my paperback book cover using Affinity Photo 2 (not Designer or Publisher as I am less familiar with them).
Amazon KDP has specific requirements such as using their template, and exporting as a PDF.
The Affinity Photo 2 form for exporting has a number of settings, and I am a bit confused. Here is Amazon's checklist for the cover:
Save as a PDF. Your cover must be a single PDF that includes the back cover, spine, and front cover as one image.
Flatten all transparencies. These can cause the file to print with missing or distorted content. Consult your software's documentation to learn how.
Embed your fonts. Consult your software's documentation to learn how.
Remove crop marks, color bars, template text. Crop marks are lines showing where pages should be trimmed. Color bars are strips with a series of patches used to ensure color balance during printing. Also, remove any template text, PDF creation guides, or software references.
Ensure your cover image meets the minimum resolution of 300 DPI (dots per inch).
Optimize PDFs. Optimization is useful to reduce your file size, allowing for higher performance when transferring, uploading, viewing, and printing the files.
Questions:
Should I flatten the entire PDF? If so, what settings should I use?
How do I embed fonts?
How do I optimize the PDF?
Thanks.
