Trying out my new USB microscope, and came upon this item. The upper right-hand outer line seems broken. What can cause this? Oversoaking?

On a line engraved intaglio printied stamp, that litle ridge of metal that is turned has broken off of the plate, and is now twisted out of line. Every time this position is inked and printed, the stamp will have that open border line. Thats the short verision.

That is not how recess engraving works.

The line in that stamp above was printed from the ink in the
recess or groove of the plate being pressed onto the paper.

If you're talking about typography printing then your
comment would make sense.

Here is a simple diagram showing different print methods.



(a) Typography (Letterpress) relief, raised

(b) Engraving (intaglio, recess, gravure ) recess, below the surface

(c) Lithography (Offset ) surface, on the surface

Thanks for everyone's input. Always a good exchange of ideas here on SCF. As you can see in the large picture, there is also evidence of small line breaks down the entire right side. Is it possible that the ink was incompletely transferred and broke off/moved somewhere during the drying process? (Just a thought ... I slept at a Motel 6 last night.)
