If it was, then the series would have to have been printed by some other method than offset lithography. I only have one high number, but didn't see any indication that it was different in any way from a regular 52 Topps.
The process works by having plates that will absorb moisture from water treated so there are areas that repel water that the oil based ink can stick to. So water soluble ink wouldn't work well at all. The new vegetable oil based inks may be water soluble, but at the time they either didn't exist or would have been really unusual.
