    Hi all: new member, first post, under deadline. Thanks for any help you can lend while I wait to hear back from Lulu.com.

    I am nearly finished with my project, a 290-page coil-bound print book with 467 music notation and illustration images. I am using Lulu’s templates and PDF job options with Adobe InDesign CC 2019 (macOS Mojave). I’m creating this update from scratch; my previous 2003 version dates back to PageMaker 6 and other dinosaurs, and I’m moving my print jobs to Lulu, so my learning process has been quite the adventure. So far, so good, and lots learned for future updates and new projects.

    Images (all .tif) were edited in Photoshop CC 2019 as needed to 300 ppi. Fortunately, thanks to the Internet, I found David’s article that tells me I didn’t need to convert images in Photoshop before importing to InDesign. I didn’t. :)

    I was told yesterday by Lulu that I need to submit my PDF with CMYK color. 416 of my 467 black/white images are RGB; others are CMYK or grayscale. Using their PDF job options for the interior file, the Output color destination profile is sRGB IEC61966-2.1. Should I use this destination profile, or a different one, to export my non-CMYK images correctly for the PDF? Or do I need to? Will that profile take care of image conversion, font embedding, etc.?

    So: any advice while I do the weekend tap dance, before I hear back from Lulu? Or do I need to keep dancing? Many thanks!

    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?
