Found the paperwork. I got my decal paper from
http://decalpaper.com
"America's Largest Decal Supplier."
I've looked at various sites, and none of them offer decal papers in different grades. Nor do they boast that their papers are better than anyone else's. This seems to confirm my suspicion that all the inkjet decal paper in the world is made in the Sunny Scopa decal factory in S. Korea.
