Hello,
As previously announced
Kindle Comic Converter 3.7 now have output profiles for all E-Ink Kobo devices.
Fully automatic creation of Kobo optimized CBZ files is now trivial
Sample files created by KCC
Some technical details...
All profiles excluding Aura HD create images x1.5 bigger than device screen. This way zoom should have high quality. Downscaling work on Kobo well enough so it should not decrease quality of non-zoomed image.
Aura HD profile create images with size equal to the size of the screen.
As always: constructive feedback is more than welcome.
