Are you referring to creating a PDF with ProPhoto or RGB images, and then using the PDF to Book option which is available at the link you provided? SOLUTION #1 LR's book module is Blurb's 'PDF To Book' process with a GUI that provides selection of book size, cover type, paper type, logo page, estimated price, layout controls, and file upload utility. When you select 'Blurb' at the top of 'Book Settings you see all of these options. If you select 'PDF' as the 'Book Setting' additional settings appear for JPEG quality, color profile, file resolution (s/b 300dpi), and sharpening. These are only applied when you 'Export Book to PDF with Book type 'PDF' selected, not 'Blurb.' When using the Blurb setting the PDF is output at 300 ppi, sRGB, Quality ??, and a fixed sharpening setting probably based on paper type selected. The PDF output appears to be otherwise identical for both the Blurb and PDF settings. So instead of using LR's 'Send Book to Blurb' button you would manually upload your 'PDF' settings created export file here: http://www.blurb.com/pdf-to-book Here you enter your book specifications for size & orientation, page count, paper type, cover type, and additional information required to place the order. You then upload your book 'Export to PDF file.' I suggest adding a comment in the description field that states the PDF uses Adobe RGB color profile images, which they will discover when the RIP conversion to CMYK. You can contact Blurb Customer Support and present them with this workflow to verify there are no issues. SOLUTION #2 Simply use the LR Book module and process your images as per the suggestions here. Submit a test book and if the results meet your expectations you're done! If not you may may want to print another test book using Solution #1 with the 'PDF To Book' workflow.
