Hi, our RGB to CMYK conversion process does not like greyscale images in indexed colour mode, which is the way Quark converts them in it's PDFing process. Customer can't convert to ID, so I'd really like to create a Preflight Profile to provide them to identify future occurrences, but can't find a rule segment that does this. Customer doesn't have PitStop, so Acrobat prefllight appears to be our only hope. Any guidance on how to achieve this would be greatly appreciated. Thanks,
Mike
