[Lab] printing on aluminium

[Bruce]

Thanks for all the replies.  To be specific, I'm not looking for etching.  I'm 
looking to print a photo on aluminium with dimension of gallery size prints.  


Again thanks to all for taking the time to reply.

   Here's a link to an acid etching process.

   Note that their process is somewhat toxic - but less toxic than the 
standard acid bath etching.

You can mark annodized aluminum quite easily using a laser cutter/engraver 
(such as the one at modlab). Resulting in a nice permanent and durable image.


See http://www.instructables.com/id/Laser-Etching-Anodized-Aluminum/ for one 
example (using an epilog laser same as modlab).

I'm doing research into printing (photos) on aluminium.  I'm looking at a
number of questions.

- Ink types.
- longevity.
- methods and materials.
- processes if more than one.
-Also interested in what is being used as a varnish or sealer.

My understanding of aluminium is that it corrodes easily so how do that effect
the final product?


If you have any information on this I'd really like to hear from you.


PS. I've talked to a few printers that do this, they are understandably or
not, quite closed mouthed about the above questions.
