Hi, Damn... I was hoping this would never happened.
The filter is right. ICC spec states pseq is a *required* tag for devicelink profiles. Seen from this perspective the devicelink generated by icclink is not 100% compliant, and thus it can be legitime to refuse it. But back to real world, pseq is just an informative tag that holds textual information about the profiles involved in the linking. The CMM needs not this info for anything but to display a nice notice. Even more, many CMM does not require it at all (lcms, for example). At that point, and since lcms can generate devicelinks not coming from profiles, I decided to avoid the tag. A bad move. Ok, I'm going to add it. Since that is a minor change, I could also pack some recent fixups and make a new release. I'm sending another message on this subject. As a temporary workaround, you could apply this devicelink to TIFF files by using tifficc utility: tifficc -l devicelink.icc tiffin.tif tiffout.tif I will try to have the new release with this fixed in a few. P.D. Very glad to have you here.

Cool....!! Unfortynately, the quartz filtes from panther is not accepting the profile. The colorsync utility says: tag: pseq is missing, repairing is not possible.
