Black comes out dull when engraving Rowmark

[Frederic Gagnon]

I am using gold and silver metallic sheets of Rowmark Lasermax for a set of plaques. The thing is, I never found a suitable way to obtain a dark black color when I engrave them. I have a close-up picture to show what I mean.
I once used Armor-All (a plastic shiner for cars) but the results are uneven. Any other suggestions?

Thanks!

I usually engrave at 500dpi resolution. And I think mineral spirits will give you a blacker look. Be sure you're removing all the cap as well.

I've never had that problem has to be something with your settings. Looks like with that texture that it could be the resolution as Mike said, or maybe using too much power.

I'm engraving at 500dpi resolution and 60% power, and full speed. I have a 65w laser. When I reduce the power, the metallic layer is not fully engraved on the edges.

I will try reducing the speed and power...

Spray the plate with either Pledge furniture spray or "spray 'n cook" cooking oil.
Will bring out the black and actually increase abraision resistance and clean it and make it shine.
We have a spray called "MR MIN" here in SA that works well.

Are you sure they sent you Lasermax, and not the rotary material?

I hope your tube is OK. I do lasermax metals on my 45 watt at 55" power 400 dpi and get a nice clean black image.
