I've built a PDF from an .afpub file. The text in the PDF uses several OpenType features, these were applied to the text via the Typography panel in Publisher.
The OpenType features include many number sets – Figure style, Caps to small caps, Numerator, Subscript, Fractions etc.
All style correctly and the PDF built perfectly OK.
Next I place the PDF pages into a new .afpub doc in order to set up an 8 page imposition – to print duplex on A4.
All appears OK except for where the OpenType features are used. The Text in the placed PDF has stripped out the OT features.
The only way to get the OT features back is to Edit the placed PDF and apply all the features again. Obviously when I update the master PDF, I have to Edit the placed PDF again.
I can send files if required.
