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?

Back when I did a little sal****er sailing, I was
struck by the irony of SS rusting, but pop cans
staying intact for years in a marine environment.

I think there's some kind of acrylic coating over
top of the printing.

Ink-jet printing. They use a special ink that is cured with UV.

Well, if you just want to remove it, 1000°F does the trick.

Even then, it leaves some shmutz stuck to the metal in the pattern of the
printing though!

I thought this was a great idea - so I tried it.

Round one - Forgot to remove the soda first. Exploded in my oven. Made one
heck of a mess. Clean up costs $15

Round two - Removed the soda and tried again. Melted the can onto the
bottom of my oven. Made one heck of a mess. Clean up cost $300

Round three - I decided to write a humorous post about how I tried something
I didn't really do based on some advice that I presume was meant in jest
because of the malicious simley face. grin

Silk-screening, then a coat of what they called 'varnish'. Saw it on
'How It's Made'. The inside of the can is coated with the same stuff to
prevent soda from eating through the paper-thin aluminum. Must be some
tough stuff.

Here is an interesting article on soda cans and about technology to print on
them.
http://www.memagazine.org/backissues...ndo/cando.html
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.
