Could someone advise?
\setupcolors[rgb=no] to avoid rgb colors, or \setupcolors[state=stop] to force black and white. You must ensure yourself that your images are just black and white / greyscale (not in RGB mode). ConTeXt does some automatical checks and conversions depending on the PDF/X standard, but I’m not sure how far that goes (e.g. PDF/X-1 prohibits transparencies, and ConTeXt cares for that).
