Marking aluminium with Spectrumark

I have been trying for a while to find a way of marking our school MacBooks and iPads for security that would look professional and not cost too much or take too long.

I have used Spectrumark spray (SLTSC1201BK) and 100%, 3 passes and 500mm min laser fill and the results are promising.


Craig, we have great results with Spectrumark in 1 pass at 500mm/min. This is on brand new and very clean stainless steel.

Perhaps aluminium behaves differently because of it’s ability to dissipate heat very well.

I am hoping other users who have experimented with aluminium may chime in with some suggestions.
