    Has anyone else noticed that pdf files using CMYK colours are now rendering properly whereas previously the colours were garish at best or inverted at worst (google "iOS cmyk pdf" to see complaints)? I'm guessing this is new in 9.3 but perhaps I just haven't been paying attention.

    This is huge for me as for years I've had to use Adobe Reader solely to view illustrated books and docs that other viewers using the Apple pdf renderer (e.g. iBooks or Good Reader) would mess up. It has always annoyed me that Apple with its focus on design has ignored this issue in iOS.

    There are still very subtle differences between Adobe- & Apple-rendered images but the new Apple ones are perfectly acceptable.

    Finally! No more need to open in Acrobat. Thanks for the find.

    Yes I knew, read it in two german blogs.

    And it seems, that Apple integrates the whole color management from OS X so not only cmyk is rendered in a standard profile (but does not recognize specific encapsulated cmyk profiles as OS X never did, too). But all integrated RGB Profiles are recognized well!

    Glad to see this. My company proposals always had a few weird color oddities in prior versions.
