Well, I got it figured out. I ordered some AN glass from Focalpoint, took my glassless carrier, removed the top, drilled a bunch of holes to perforate where I wanted the metal to be broken off and then bent it off. Then, as I started filing away at it to get rid of the jagged edges, I noticed a pattern that I actually kind of liked. So not only can I print the entire frame including the notch code, I have a "Postage Stamp" look for when I want to really bring something fresh to a series, like portraits...

By the way, I am blown away by how easy it is to make superb prints from 4x5 compared to smaller formats, it feels almost like cheating..:-)

I'd love to show it to you, but I can not get any size attachment to load...
