How does a soda can manufacturer print the logo and info on an aluminum
can? I thought maybe they were color anodized at first because they are so
durable, but after closer inspection and playing around, I think it is
some kind of super durable ink spray or silk screen process.

Acetone doesn't touch it and even a wire wheel takes a slow or deliberate
pass to remove it all.

Anyone know for sure?

Here is an interesting article on soda cans and about technology to print on
them.

Can you believe they can print cans at the rate of 2,400 cans a minute?

This article leads me to believe that the varnish they put over the outside
printing is different from what is sprayed on the inside to coat the can.
