How to get a stronger distinction during laser engraving on stone?
In order to attain a stronger distinction, you'll be able to fill the engraving with synthetic resin or lacquer. particularly within the case of polished stones, the lacquer or the resin adheres significantly well to the carved (and therefore roughened) surface.
What should be taken into consideration when engraving photos?
