I am switching over to InDesign CS6 to create EPUB files. Never had an issue with CS5.5 or earlier version.

Just exported my first EPUB and tried opening it in Calibre and it reports that the file is locked with DRM. There is NO DRM on the file. BTW, it opens fine in Sigil.

I exported the same file in CS5.5 and it works fine. Anyone have this issue before?

Thanks

No idea but I do want to mention, if you don't find answers here, you might want to try the indesignsecrets.com message boards. I know there are people there using InDesign to create ePubs.

It is likely that you have embedded fonts that are encrypted, and Calibre is misidentifying this as a DRM'd book. I would suggest mentioning it on the Calibre boards, since Calibre should be able to detect this and not treat it as a DRM'd book.

On a suggestion by another user, I recreated the file without embedding fonts and the error disappeared.

The odd thing about this was that exporting the same book from InDesign CS5.5 with embedded fonts did not produce the DRM error.

So, the real question is: what is InDesign CS6 doing that produces an error, when CS5.5 doesn't?

Calibre is capable of dealing with Adobe's font obfuscation scheme (or at least it was). I suppose it's possible that they (Adobe) slightly altered the manner in which fonts are being encrypted (with CS6) and it's tripping up calibre. Or it's possible there's a bug in CS6. But in either of those cases ... I suspect it would be tripping up some other readers (devices/apps) as well.

Have you tried opening it with Adobe Digital Editions, Nook for PC, or another epub device/app to see if there's an issue there (and that the embedded fonts, in fact, display as expected) when using the CS6 output?
