Laser Compatibility
Engrave from the BACK side for best results — laser removes protective coating and reveals mirror beneath. CO2: engrave 250mm/s 20-30%; cut 3mm at 15mm/s 80W. Diode: engrave 200mm/s 70-80% from back. Do not engrave from front — damages mirror coating unevenly. Use masking tape to protect surface during cutting.
