Have a customer that was looking for small plates to install on the superchargers that he installs at his shop. Was looking to use Laserbond100 but found these AlumaMark 3x1 plates. These are pre-treated so that when you etch with the laser, black stands out. Did 600 speed, Full Power, 340 LPI for the engraving, and 500 speed on the scoring. I may tweak the speed some more on the scoring due to some little squiggles.
Overall, happy how they turned out. FYI, AlumaMark only works on 1 side (the one with the plastic protector that you peel off before etching)
