Aperture Print Options

Good morning,

I am (still) working on my first Blurb Book. For various reasons, I’d like to produce them from within Aperture. My pictures are either RAW or JPEGs froms an iPhone. I have followed the instructions regarding the size/margins of the book as described in this forum.

I am now  ready to produce a PDF and upload to Blurb. I understand the concept of softproofing and the Blurb ICC profile has been used. However, I am unclear as how to set the export preferences in Aperture. I have included the ownes associated with color profiles and would very much appreciate if someone could help (sorry, cannot get the links to show up inline.
