Hopefully this article helps.īefore anything is marked with the laser, there is one question to consider: Will the mark that is made, even if color-filled, be darker or lighter than the material being marked? If darker, there is no need to invert the graphic. But I’ve seen enough examples of completed works, done by skilled craft people, that failed in this regard, so there must be some confusion regarding it. Many may question the need for an article on something so basic. The subject of inverting graphics is easy enough to understand. In order to create a positive image, the graphics in the drawing need to be inverted. What’s black in the drawing translates to stainless steel on the tumbler and a negative image is engraved. Much like writing with chalk on a blackboard, the laser vaporizes the coating and exposes the stainless steel underneath, making a light contrasting mark on the tumbler. It looks like a negative! What just happened? You clean it up a bit and… it doesn’t look quite right. Using the same graphic, you run a job that vaporizes the color to expose the stainless steel underneath. Then you’re given some black powder-coated tumblers to mark. They all turn out great, with a dark contrasting result. You’ve been marking school logos on stainless-steel tumblers using laser marking material for months.
