And this mistake was not visible to my eye when viewing the converted images on screen! They looked a shade darker, but nothing like they printed at the litho.
To fix this, should I go back to the original RGB images and leave conversion to CMYK until the output to PDF? Will this avoid the 'Pure Black' trap?
Indeed, how does one convert images to CMYK safely? Just turn off 'Preserve Pure Black' for each conversion, and back on again for the text?
I also notice in the Soft Proofing dialogue a box called 'Preserve CMYK numbers'. Should that be checked?
Any help with this would be gratefully appreciated!

Preserve pure black is not checked by default, if it's on turn it off. Map gray to CMYK black should be checked by default.
I would suggest setting rendering intent to perceptual instead of relative colorimetric. Make sure Photo-PAINTs color management matches Draw. I.E same profiles and rendering intent.
Let Draw embed the images, convert them via edit bitmap, taking them into Photo-PAINT to convert to CMYK, save the Draw file after importing each image, size the image and resample the resolution to what's required for output, then convert to CMYK in PP.
Use the default Press PDF settings in Draw you may want to convert fonts to curves in the PDF settings.
Thanks David,
Just that other setting 'Preserve CMYK numbers' in Draw's Proof dialogue - should that be on or off?
Also, when I convert an image to CMYK in PP, should I embed the ICC Profile? I see that the profile gets embedded again in the PDF export. I presume it doesn't get embedded twice?
