Correct Settings When Using CerMark for Engraving Glass
The settings on your laser can make it or break it.
Using the correct power and speed settings for your laser is critical when working with CerMark on glass. I recommend using a power setting of 100 percent. The speed setting for the laser should be set using the formula of taking the rated laser power as the speed setting. If you have a 50-watt laser system, set the speed to 50 percent.
Keep in mind that the laser bonding process for CerMark on glass works a little differently than you are used to. The focused heat energy from the laser will cause the CerMark to bond to the glass. However, an engraving speed that is too slow will have too much heat energy and cause the glass to chip and flake off. The engraving result will be a coarse look that is gray in color. Conversely, an engraving speed that is too fast will not allow the CerMark to bond to the glass, looking patchy with sections of engraving missing.
