Production guidance

This ANODIZED ALUMINUM - UV Engrave metal record pairs 60% power with 600 mm/s on UV 355nm 5W, using 1 pass, 130 kHz, 0.02 mm hatch spacing, and 1 ns pulse width. Compare every listed field with the source, lens, focus method, and material finish on your machine before transferring the recipe.

1. 1. UV ablates anodized dye to expose bare aluminum. Crisp white mark on colored anodize. Source: ComMarker Omni UV guide (2024).
2. 2. Treat this as an unverified baseline, not a production preset. A VERIFIED Parameters Library record requires three independent community vouches; an attached proof-burn image provides additional evidence.
3. 3. Bare metal is unforgiving of focus error: re-zero on the actual work surface rather than the bed, and wipe oils off before marking or the mark will read blotchy.
4. 4. UV marks cold, so contrast comes from surface chemistry rather than heat. Focus tolerance is tight; a fraction of a millimetre off will wash the mark out.
5. 5. A 0.02 mm hatch is fine enough that overlap error shows: verify the galvo or gantry is square before running a large field.
6. 6. Record the successful result in the Parameters Library so the next production run is repeatable.

The bundled note for this ANODIZED ALUMINUM - UV Engrave recipe is: “UV ablates anodized dye to expose bare aluminum. Crisp white mark on colored anodize. Source: ComMarker Omni UV guide (2024).” The source data was reviewed 2026-08-09; no independent vouch or proof-burn image is attached. Label the scrap test with the adjusted values and keep the accepted result with the production job.
