What's the standard procedure for placing an externally supplied advert into a document that includes crop marks? I'm placing ads in a conference brochure and in removing the crop marks I seem to be removing small portions of the supplied artwork?
If the advert is not going to bleed (presumably it won't) then you should be holding shift when clicking "Open..." and choosing "Crop to:". Select "Trim" and you shouldn't get the crop marks.
That's exactly what I needed, thanks!
