“How do I get a stronger contrast when laser engraving on stone?”
To achieve a strong, contrasted effect on stones, you have the option of physically filling in the engraving marks with a synthetic resin or lacquer once you are finished laser processing the material. Especially in the case of polished, smooth stones, these resins and lacquers adhere particularly well to the engraved and roughened material.
“What do I need to consider when engraving photos onto stone?”
Unfortunately, it is impossible to find a stone that is completely and 100% smooth. Due to this, stones are usually best suited for coarsely rasterised images – 250-333dpi. Very fine and detailed images may be difficult to achieve under certain circumstances. However, this very much depends on the structure of your chosen workpiece, including size, colour, density and type.
We usually recommend keeping your lines thick and your graphics simple when it comes to stone engraving. But the sky is your only limit – show us what you can do!
