It's waterproof on paper, don't know about on a slick nonporous
surface. I can tell you from experience that anything not able to
quickly and completely absorb the ink will cause severe puddling of
the ink.

Almost all stock Canon black inks are pigmented, until you get into
the 6 and 7 color photo printers. Many of them have dual black tanks,
the BCI-3 black is pigment, and the 6 is dye. I have several Canon BJC
6000 for my digital photo business, and I've seen what happens on
paper that is not absorbent enough, or if I accidentally stick a sheet
of laser transparency in it.

But don't let me stop you from trying. Just sharing what I know.
