Production guidance

This GLASS (Clear) - UV Engrave glass record pairs 90% power with 300 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 subsurface glass marking. Cold process - minimal cracking. Source: ComMarker Omni X; jimani-inc.com (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. Glass chips rather than ablates. A wet paper mask or dish soap film spreads the heat and is usually the difference between a frosted mark and a cracked piece.
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 GLASS (Clear) - UV Engrave recipe is: “UV subsurface glass marking. Cold process - minimal cracking. Source: ComMarker Omni X; jimani-inc.com (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.
