Production guidance

This ACRYLIC (Clear/Cast) - UV Engrave acrylic record pairs 80% power with 400 mm/s on UV 355nm 5W, using 1 pass, 100 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 engrave on clear acrylic - cold process, no melting. Unique vs CO2/diode. Source: ComMarker Omni UV application 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. Cast and extruded acrylic behave differently at the same settings — cast frosts white and extruded tends to melt, so confirm which sheet you have before trusting these numbers.
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 ACRYLIC (Clear/Cast) - UV Engrave recipe is: “UV engrave on clear acrylic - cold process, no melting. Unique vs CO2/diode. Source: ComMarker Omni UV application 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.
