    pink/red? Nooo...

    but here's the plate again, first I scrubbed the engraving with Ajax cleanser and a toothbrush, and for good measure I ran a Magic Eraser over it a few times, you can see it dulled the lacquer finish--

    Results: This is the 'naked eye' version, still looks very black in this pic, and to the naked eye...

    This is the 'honest' version, I set the plate on my knee and made sure the overhead light was hitting it squarely...

    --as you'll see in the full size pic, the underlying color is dark brown, but that's typical when burning metal with a fiber...
    However, the dark is in there, it's not just dark ash that will wash away

    @Kev That looks great, I would have taken your word for it. I just wondered since I had the burn that wiped away before I got true black. I played with my setting some more and came up with a black that stays put. I also ran Tykma's manual with settings for brass and with a little variation I was able to get the types of marks they reference in their manual. Mostly just lowering power since they were using a 20w and I've got a 30. The fiber laser is like an Adobe product, a dozen or more ways to get the same end result! Lol

    The Red is kind of purple in the photo but resembles the Red Rocks of Sedona and the Pink I think is a little more orange than pink. Still interesting that it's possible for something other than Black and White on Brass.
