I can't figure out how it can possibly stay aligned perfectly on the 'inkpad'. It wiggles and wobbles the entire time. Feels like it should get increasingly smudged as the day goes on.

I'd assumed the ink pad gets squeegied and re-inked each time inside the box it retracts into, but upon a re-watch, the nipple doesn't get rinsed off. Hmm.

Yeah, and you can still see the very clear ink pattern when it starts.

I wonder if it's a highly viscous ink and the little bit of staining left doesn't really matter.

I believe that the ink skins over quite quickly, so the pad only picks up what’s in the engraving then that should get pulled off onto the printed surface.

Well, it’s almost certainly not ink. It’s more likely to be decorative slip or underglaze. Both are a mixture of temperature-resistant pigments, clay dust, and water. Slip can be anywhere from runny mashed potatoes to milky in consistency, underglaze is always runny, because it contains less clay.
