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.<div><br></div><div>See <a href="http://www.instructables.com/id/Laser-Etching-Anodized-Aluminum/">http://www.instructables.com/id/Laser-Etching-Anodized-Aluminum/</a> for one example (using an epilog laser same as modlab).</div>

Hello,<br>
<br>
I'm doing research into printing (photos) on aluminium. I'm looking at a<br>
number of questions.<br>
<br>
- Ink types.<br>
- longevity.<br>
- methods and materials.<br>
- processes if more than one.<br>
-Also interested in what is being used as a varnish or sealer.<br>
<br>
My understanding of aluminium is that it corrodes easily so how do that effect<br>
the final product?<br>
<br>
<br>
If you have any information on this I'd really like to hear from you.<br>
<br>
<br>
PS. I've talked to a few printers that do this, they are understandably or<br>
not, quite closed mouthed about the above questions.<br>
