Jewelers Benchpin Forums

The following testing was done on a 14 karat yellow gold disc that was approximately 0.75 mm - 1.00 mm thick. Using the following settings I was able to get insanely fine details and clear legibility with text that was less than 1mm in size.

• Image [SVG image with a solid black image on a transparent background]
• Engrave
• Fiber IR laser type
• 150 microns dot duration
• 1 - 100 % power range
• 1,200 dpi
• 1 pass
• Grayscale bitmap mode
• Bi-Directional engraving mode
• 30 kHz

One caveat on my testing is that I had to clean the surface after the engraving was done as it had a "slag" buildup wherever the laser passed. This was especially true with other settings, but even with the above settings there was some buildup. I conducted this testing in my home office (not shop) so I used Tabasco sauce to clean the gold. (It works wonders on copper....) I also thoroughly rinsed in water and wiped the 14 karat gold plate clean.

All close-up examinations were done at 10X magnification (with a loupe).

I will need to update or reply in this thread with Text settings on 14 karat yellow gold.
