When I first noticed the ink on the back of the stamp, it appeared to be bleed through. On further inspection it was evident that it wasn't. Am I correct when I say this is caused from stacking while the ink is still wet, causing the impression? If so, what is the technical term for it? Thanks, Jon
It is from stacking the sheets of stamps on top of each other before the ink fully dried. What you see is also a great indicator that the stamp is a Flat plate print so if you ever run across a Washington / Franklin stamp and you're having a tough time determining if it's a flat plate or rotary press check for the offset, also known as a set-off.
These used to be called "offsets" as Ken said, but I think specialists today want to avoid the unrelated connection to a machine printing method and tend to call this a "set-off" as stallzer said.

Thanks. I too, did not know that the 21st century had updated the language.
