PDF to KFX on Kindle Scribe

[apastuszak]

I'm converting PDFs to print replica KFX files for my Kindle Scribe and I am having an odd issue with covers showing up on the Kindle for all files.

Here is my process:

1. Convert the PDF to greyscale using the following command:

gs -sDEVICE=pdfwrite -sProcessColorModel=DeviceGray -sColorConversionStrategy=Gray -dOverrideICC -o bw-converted.pdf -f original-file.pdf

2. Create kpf file using Kindle create by making a print replica file.

3. Use the following command to convert the kpf to kfx:

calibre-debug -r "KFX Output" -- bw-converted.kpf  "bw-converted.kfx"

I thern import the file into calibre and sync it over to the Scribe.

Sometimes I get covers and sometimes I don't.

Any idea on how to force the covers across?
