I got some aluminum business card blanks an did engraving tests today. I am having a hard time getting a nice sharp image like I saw @Xabbess post… At any legible power/speed combo I get some blooming that obscures detail. The best settings I developed are also pretty different than I have seen on other anodized project posts–much lower power.
Because I am able to mark this stuff at super low power and top speed, I wonder if this is some kind of ink coating and not actually anodized? The only colors sold were printer’s cyan, magenta, yellow, and black, which really makes me suspicious too!
(I have a few anodized blank rounds from Ringlord and these business cards are definitely more shiny, but I haven’t tried engraving on the Ringlord products yet.)
(What you cannot see clearly in the photo is that the speed 1000/power 12 test isn’t all the way through the blue layer.)
