Reply To: Convert images to CMYK

David, I still wouldn’t advise anyone but advanced artworkers to convert from InDesign, even if the technology is the same, as there are too many pitfalls for the unprepared. If an artworker is happy to use an RGB workflow without considering the whole document, what will happen to the glorious red text in her image that brand guidelines specifies should be 0 100 100 0? Under PDF/X-1a that will be thrown out as 0 95 85 0. Not to mention the vector RBG logo she’s pulled in from Illustrator, for a start it will be wrong and unless she’s dug through the menus to find the profile settings in Illy and Photoshop, the conversion wont be the same even in those programs.

So even though the strict answer to the OP’s question is ‘yes, that’s fine’ I think there’s a minefield waiting for those who merrily pick a PDF standard and export without thinking it end to end. Perhaps your blog post can be titled ‘Holistic Colour Management’…
