Dear Luigi and Hans, I have the following sample: \setupbackend [format=PDF/A-3a, intent=sRGB IEC61966-2.1, profile={sRGB.icc,default_gray.icc}, level=0] \setuptagging[state=start] \setupcolors[cmyk=no, pagecolormodel=auto] \setupexternalfigure[location=default] \startTEXpage[offset=1em, align=center] \dontleavehmode \externalfigure[cow-black] \dontleavehmode \externalfigure[cow-brown] \dontleavehmode \externalfigure[basic-figures.pdf][scale=200] \stopTEXpage \stoptext The third external figure is found at http://pdf.ousia.tk/basic-figures.pdf. I included it, since it adds a transparency group (and I guess this might be relevant). PDF/A-3a validation (http://verapdf.org) warns about XObjects not having any ICC profile. Would it be possible to add the "profile" key to \externalfigure, so that each figure may have its own profile (or the reference to the profile) added? Many thanks for your help, Pablo -- http://www.ousia.tk
