That is a good question derezzed.
SP is already aware of the set and what it looks like, so I sort of feel that if they weren't confident that their equipment could faithfully produce it, I don't think they would have proposed making it a Set of the Month. But, of course, we won't know for certain until we try some experiments. It will be an iterative process that will take a little time.
My biggest fear is being told that in order to be "safe" and avoid any chance of sublimating over the top edges, I will have to shrink the graphics to a size smaller than I am happy with. The EDSP graphics I'm not so worried about since they all have lots of open space around their printed elements. It is the Semiotic symbols that present the greatest potential for problems because they all have a red border which must be perfectly centered and not run over any top edge. Depending on the registration tolerances of their sublimation equipment, this could be a thorny issue.
