I'm not sure sure there's any real aesthetic advantage to printing 
to the edge of the image, and staining, dirt, moisture etc. are much 
more of a concern. Are we fairly sure at this point of the long-term 
integrity of these coatings? I remeber Paul Roark posted something 
about that, but the details escape me right now.
