Re: should I embed or link photos in Illy for mag ad?
Embedding "photos" (images) or any other artwork in Illustrator as opposed to placing with links has some real disadvantages:
(1) You lose the flexibility to edit the photos without explicitly editing the Illustrator file.
(2) Embedding the photos forces you to convert the photos to the Illustrator file's color space at placement time. This could seriously limit your printing options. For example, assume that your ad in Illustrator is CMYK. If you embed an ICC profile-tagged RGB photo, that photo will be converted to your Illustrator file's CMYK color space immediately. When you send to print or save as a PDF file, you end up with everything in the CMYK color space. On the other hand, if you place with a link, the photo's original color space is preserved. When you print or save as PDF, you have the option of maintaining the photo's original color space (with the original ICC profile, of course). This gives you many more options for repurposing, high fidelity printing (more than four colors such as Hexachrome, etc.), etc., options that are not available if you prematurely dumb down the photos' color space to CMYK!
