    Aluminium Engraving

    Hi All,

    I have never engraved aluminium, just had no demand until now. As I understand it, most folks engrave anodised aluminium. I have been asked to engrave something similar to the attached image, this is a bare aluminium with a black/grey engrave mark. How would I achieve this? Would I use cermark? Would this be better on a cnc, but getting the tones would be awkward.

    Any help would be much appreciated.

    There are silver aluminum that engraves black. Alumark and LazerBlak are two. That's what I'd recommend.

    Thanks Ross, I will have a look around for a supplier locally.

    For gray areas I drop the resolution and shoot a 40% gray.

    When you do Cermark, think of the way newspapers do shading... dot saturation. Also, be prepared for a learning curve with Cermark. For my 40w Helix on Yeti mugs, I have to make the coating area near opaque with LMM-6000 to get a good black mark @ 20s/100p/300d/Stucki. Even then the grain from the steel peeks through.
