PDF 2.0 spec will add explicit BPC (black point compensation) support in the file format, which means the ability to set a per object flag for BPC on or off. And that should be considered since perceptual and relcol transforms aren't ideal for most images, in an ICC v2 context. (In v4, perceptual would be the default intent. In v2, relcol + bpc should be the default.)<br>

You may want multiple OutputIntents. Currently all of these specs use just one, following a "one PDF, one output device condition" sort of philosophy. But it's imaginable having a single print job for a small book and cover, where there are different intents for the cover, and the interior stock. Or a book that's mostly black and white but with some color image inserts in the middle of the book.<br>

Anyway, I think in the near term PDF/X-4 along with BPC support make the most sense to me.<br>
