I made quite a few of these for people restoring old automobiles and putting on machinery. I use alumimark material on my Epilog 24TT using 30 speed and 10 power with the focus about 1/16" above focus point.

Al,
As long as you realize the darkening is temporary... if someone wipes it down (say, with alcohol), it goes back to the dull black.

Mike, is color laser transfer not suitable because of the "reverse video" effect with large black areas and "white" lettering? If it were black text on aluminum, would color laser transfer be suitable? Or do you feel that it still would not stand up to abuse in either case?
I have been considering buying equipment to do color laser transfer for legends on aluminum control panels (mainly black) but if you think it is not durable enough then I would like to know. Also, is it feasible to overcoat the black toner to make it more durable?

I would not use CLT in any application where it may be subject to use or wear or frequent cleaning. The only application on metal is for a plaque which, of course would get no handling or wear.
I use it for black on brass or aluminum plaque labels and my most common use is for name tags where I prefer to transfer it to white engraving laminate. It holds up well and because of the matte finish of the engraving plastic it will stand up t the fingernail test.
I frequently use laser sublimation for black on brass or aluminum as it cannot be removed. It will, over time, give in to uv deterioration.
This example is on brass but I use it on standard engraving aluminum in both brushed brass and polished aluminum.
