BEHost / Tuesday, March 22, 2022 / Categories: Laser Marking FAQ's Laser marks are spotty Question- When using the ULTRA spray on stainless steel tags we are getting spotty results. Not solid black. I have a 25 watt universal M300 laser. Experiencing faintness in some areas of the tag. Our settings are power 100 and speed of 20. PPI of 600. Answer- https://jorlink.com/laser-supplies/cermarkthermark/thermark-how-to-use/laser-settings-chart . These are suggested starting settings. All of the laser spray products will require some experimenting to perfect. Even two lasers that are the same brand, model and power will be different. Over time the laser tube will change in power and that will effect the results. More power does NOT mean better results. There is a sweet spot you'll want to find.
