Adding more info, as I just get them about printing companies in the US:
Another facility was printing MTG cards: PBM Graphics, Inc.

Adding quotes here with some important info, as not everyone is on FB or want to be there:
Did wizards use them for printing?
They did. Also Pokemon when Wizards had that license, Harry Potter, dragon ball z, and a host of sports cards (Topps etc)
I remember most specifically the P3K set when I first came on board. There were piles of these just sitting out on the floor ready for destruction ( mostly rejected sheets and overage ). Funny thing was that I had played magic for years and never knew that the company I was about to work for was printing them.
Me: Do you have the list of all the MTG Editions, Extensions printed by PBM Graphics, was only P3K printed there ? Trying to solve a mystery of Glossy P3K Vs Regular ones. Thanks for helping
Actually I don't know. They still print magic though. I do remember we did a lot of testing with coatings for many runs. As for P3K, I think Yaquinto may have had that run too. We released a lot of sets in tandem. It wasn't uncommon for product to be compared ( we would receive samples from carti mundi and Yaquinto ) to keep consistent product quality.
Me: Do you remember the First printed set done by PBM Graphics North Carolina ? This is breaking news for me, as I collect this kind of info for historical purpose on my MTG website.
Alexis, I would have to think back on it, I remember 7th, all the saga sets, invasion block, odyssey, Garfield finkle, beat down, too many.
