Every diaper looks pretty much exactly the same. The fact that they can do that allows for prints designed for specifically the back and front, for example.
All other ABDL diapers don't have that. They have some kind of repeating pattern. The exact positions of elements of the print is different for each diaper, which must have something to do with how the machines work. I imagine they cut printed plastic from a huge roll of plastic. If you have a whole diaper design (as I called it) the machine needs to cut the plastic at the right location, otherwise the design appears shifted on the next diaper. That's difficult, apparently. The easy solution is to use a pattern where it doesn't really matter where it's cut.
