Question

Converting EPUB to MOBI seems to work locally but fails KDP validation

We are new inDesign users (learning it for about 2 months). We created a children's Illustrated book - about 40 pages, full spread pictures, etc. We exported it to a fixed layout EPUB. It looks fine in the "Kindle Previewer" and we generated a MOBI file from the "Kindle Previewer".. Re-opened the mobi file and it looked good (as expected).

 

When we uploaded it to KDP, we had a "Quality issue" opened against it for "Formatting - Overlapping text". We went back and forth a couple of times, uploaded new versions, but still couldn't get beyond the issue.. Their support sent us a picture of what they were seeing, and the Fonts used in version they have are not the fonts that we had in the book - the text is "scrunched" together in (guessing) what looks like a basic or default font.

 

We went back to the EPUB, renamed it to a ZIP file and unzipped it... We can see the fonts included in it. I wasn't sure how to look at the MOBI to see if it may be missing the fonts so I also downloaded "Kindle for PC" to a couple of separate computers and verified the generated MOBI loads and looked fine on both of them, so we're not sure why they are not seeing the fonts? 

 

I think I read somewhere that Fonts might be stripped from MOBI files when they are uploaded to KDP?, so we just uploaded the EPUB and have yet to hear back from them... But thought I would ask just in case.

 

At this point I am almost contemplating putting the text directly in my Photoshop illustrations rather than InDesign so that they become part of the pictures. But it makes it so much harder to perform updates to text styles, fonts, etc.. Anyway, any suggestions?

 

I am using:

Adobe InDesign CC 15.0.1 x64

The epub file is a fixed format

epub version is 3.0

The embedded fonts are Adobe Fonts (from the unpacked EPUB):

  • FairyTaleJF-Regular.otf
  • Litania-Regular.otf
  • RemedyOT-Double.otf
  • RobotoSlab-Regular.ttf (all though im not sure why its there - its not used in my book)

Followup.

 

The Epub was fine - validated without issue using a free validater (https://www.ebookit.com/tools/bp/Bo/eBookIt/epub-validator) which the Amazon support person sent us to....

 

But the Epub still didn't work for upload, and the generated Mobi file (from Kindle Previewer)  had issues on the Amazon KDP side with Text displaying incorrectly..

 

We ended up exporting all of the Pages (Text, object font effects, and illustrations, etc) as high quality JPEG's and then assembled them into their own Indesign Document, and then exported it as EPUB..

 

Turned out great. I was also happy to see the font effects ( outer glow, and drop shadows worked fine as well) embedded into the document.. We generated the MOBI from Kindle Previewer without issue, and it uploaded without issue.. Good to know, will remember for later... But just thought this might help someone in the future if they run into the same problem.

It might be worth validating the ePub with FlightDeck; $15 for a month's worth.
