Sorry, Jan-Ulrich, it isn’t clear to me what is going on here. The following sample: \setupbackend [format=PDF/X-3:2002, intent={ISO Coated v2 (ECI)}] \starttext \null \stoptext gives me the following error: lpdf-fmt.lmt:282: attempt to call a nil value (global 'urls') Line 189 from the same file reads: -- When we have an URL we can assume that embedding is not needed. Line 8 from colorprofiles.xml also reads (as a comment): When the id is "Custom" we assume that embedding is needed. (Also related to line 391 from lpdf-fmt.lmt.) As far as I understand, color profiles with urls aren’t being embedded in the PDF document. For reasons totally unknown to me, lpdf-fmt.lmt has also problems with profiles from http://www.color.org. I’m afraid I cannot help here, Pablo
