In that case it wouldn't yield CMYK, however. I'd expect some sRGB profile of some kind, likely some version of the 'standard' 61966 sRGB profile (if such a beasts exist as a 'standard' - that's another story). If I don't remember wrong PDF/X-3 actually allow such colour management to pass any checks. That might explain why Pascals job actually create a PDF ...

It is unclear how simply selecting PDFX3 joboptions and using CMYK images in Microsoft Word can yield totally PDF/X3-compliant PDF unless (1) the CMYK images were in fact color-managed CMYK images from Photoshop in EPS format, (2) the R=G=B options were selected under Windows, and (3) all text and vector content of the document was truly black or grayscale. OR perhaps it was on the Mac and "think different" something affects what happened. It really help US at Adobe help customers if we could track down what "accidents" occurred in the workflow to yield what appears to be "correct" results for the customer. - Dov At 7/25/2003 01:45 PM, Jacob Sch�ffer wrote: >Dov, > >Does it really make a difference? > >Though I'm not a Mac expert it seem to me that: > >1) all MS apps print RGB on Mac even though the Mac PS driver > natively supports CMYK, >2) Apple appear to have made all sorts of weird workarounds > for the sole purpose of having the MS products run at all. > Perhaps MS also made a special effort though it seem > unlikely when judged on the PS output I've seen. > >Perhaps Apple thought they'd sell more Macs if they supported MS Office :-). > >Please correct me if you know any better! > >Best regards >Jacob Sch�ffer To change your subscription: http://www.pdfzone.com/discussions/lists-pdf.html
