Production guidance

This STAINLESS STEEL - CerMark Black (Fiber) coated record pairs 40% power with 400 mm/s on Fiber 30W, using 1 pass, 50 kHz, 0.025 mm hatch spacing, and no recorded pulse-width override. Compare every listed field with the source, lens, focus method, and material finish on your machine before transferring the recipe.

1. 1. CerMark/Brilliance spray black mark on SS. Apply thin even coat, let dry. Wash residue with water. Source: CerMark USA official guide & LightBurn forum (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. Coating thickness is the real variable. Apply evenly, let it cure fully, and re-test whenever you change spray batch or application method.
4. 4. MOPA pulse width is the parameter doing the work here — if the result drifts, adjust pulse width before touching power or speed.
5. 5. Change one variable at a time — power, then speed, then frequency — so you can attribute the improvement when you find it.
6. 6. Record the successful result in the Parameters Library so the next production run is repeatable.

The bundled note for this STAINLESS STEEL - CerMark Black (Fiber) recipe is: “CerMark/Brilliance spray black mark on SS. Apply thin even coat, let dry. Wash residue with water. Source: CerMark USA official guide & LightBurn forum (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.
