When a laser strikes glass, it fractures the surface but it will not engrave deeply or remove material. The fracturing of the glass surface will produce a frosted appearance but can cause roughness and chipping depending on the type of glass being engraved. While the frosted appearance is desired, the roughness and chipping are not. Here are some tips, which will help create smooth, bright and frosted effects on glass:

  1. 300 DPI: Using a lower resolution, around 300 DPI, produces a better result on glass as you separate the dots you are engraving.
  2. 80 Percent Grayscale: Change the black in your graphic to 80 percent black to improve the engraving quality.
  3. Jarvis Dithering: Running with a Jarvis dithering pattern in the driver (you’ll find this in the laser dashboard) will also help provide a smoother finish.
  4. Masking: Some people find that applying a thin, wet sheet of newspaper or paper towel a little larger than the engraving area also helps with heat dissipation and improves the engraving. Just be sure that there are no wrinkles in the paper after it is applied.
  5. Dish Soap: Using your finger or a paper towel, apply a thin coat of liquid dish soap-any kind will do-over the area to be engraved. This will dissipate the heat when engraving.
  6. Polish: If there are small shards of glass, you can polish the area with a ScotchBrite pad or something similar.
