Well, uhh, no. For example: a duotone, starting with 100% black and
50% magenta in Ovation ends up with 80% black, 60% magenta, 40%
yellow and some cyan in pdf. We got the prints back from the printcompany
today and it look's ... nice (printing black as black and magenta as a
spotcolour), but it's so much different from the result in former days:
printing seperated postcript files.


Two things.

(1) Have you got Direct PostScript set in OPW Print choices

(2) If you don't have Direct PostScript set (and are not using aPostScript based driver), then your CMYK colours will be converted toRGB using the settings in OPW colour choices.

I think there may be another point. How is the PDF generated? Some PDFprinter drivers work using PostScript (Adobe for example) and can beexpected to use the CMYK colour model. Others are based around Windowsmeta files (as are most printer drivers), if you use one of those thenthe print file will be turned into RGB.
