A. Hi Venki. I think you'll need to send photos, and spend several paragraphs of description to get help because you've given us no process data at all yet. It sounds like, rather than printing before sealing, you are doing UV printing on top of anodized aluminum and immediately UV curing it? ... but that the laser cutter is burning the printing in some way? ... at the cut edge or totally destroying it across the whole surface?

It's very hard to make any suggestion other than don't use UV printing or don't use laser cutting unless you give us some other facts :-)
