Here's one from Cleveland, printed in 1995, with a cropped image of the
BPN (Back Position Number 9 -seen high up not too far from "IN GOD WE TRUST:"


For me (anyway) I find it easiest to detect a WEB (compared to regular intaglio) by finding the location of the
BPN (although there are other ways to identify one).
Here's "FR-1900" a typical intaglio press "Mule" note from 1963 (where the high
BPN is below the ONE):



There are other differences as pointed out by that excellent link to Wiki but when I hold them side by side you can see that the ink seems a bit darker green on the Web-pressed note (compared to a regular run). Also, the above intaglio 1963 note seems to have that impressive, almost 3-D look that is more typical of intaglio, whereas the "Web" note's design seems a bit flatter to view in person.
