Reply To: Color destination profile for Lulu

Cynthia,
I’m confused that LULU would tell you they want cmyk PDFs, yet provided you with a job.options that specifies RGB. This wouldn’t be the first time that a printer — especially one trying to communicate across a large base of users — didn’t keep their story straight for all of us who like this level of detail.
Without confirmation by Lulu that their rgb output is indeed ok, I’d be tempted to modify their job.options to convert to cmyk with preserve numbers (this way, any cmyk content in your file is unchanged.)
Or I might be tempted to do the above, AND also create a PDF using their settings as provided.
With a traditional printer, you might be able to provide both files as a test and receive their feedback. I don’t know if Lulu does such a thing.
Is this helpful at all?
