What's the difference between Erlanger and Cincinnati factories? The Cincinnati ones are better? And what's the story behind the seals? Terribly curious.
Cincinnati, Ohio was the old factory that shut down in 2009. By about August of that year, operations had been shifted to Erlanger, Kentucky - a suburb of Cincinnati that's actually a bit closer to the metropolitan area's international airport.
There was a notable drop in quality with the shift to Kentucky. For custom decks, it was simply a "shakedown" period when they were ironing out the kinks of the new printing equipment. For the bread-and-butter products like Bicycle Rider Backs, the quality was believed to have been lowered just a tiny bit - enough for some people to at least think they've noticed it. For example, I have a pack of Tally Ho Circle Backs in a Cincinnati Box that were made in Kentucky in '10 that have inconsistent shades of color on the card backs, almost as if they'd been cut from a few different sheets from different portions of the print run.
The biggest issue in the shakedown period was noted in their custom work. They had to adjust their Bicycle stock to be just a little lighter (from about 325 g/m
2 to 300 g/m
2) in order to work better in the new Heidelburg printing press. That in itself wasn't a problem, but at some point many decks had finish issues, especially those with unusual or metallic inks - some examples would be the Stephen Rooks decks he printed with backing from Diavoli in Germany and USPC's own Bicycle Tragic Royalty deck, which used a heavy grey in on most of the cards' surfaces and a fluorescent, UV-sensitive ink on the court faces.
With the development of Magic Finish, first commercially used on Ellusionist's Gold Arcane deck as a real-world test of the product, followed by the subsequent policy change making the new coating the default finish for custom decks, the problems seem to have become a thing of the past. I'm certain the time spent learning the ins and outs of the new machines was also a contributing factor. Any custom decks and most standard decks made roughly from 2011 to present in Erlanger would likely exceed the quality of the Cincinnati plant in its final few years at the least.
