There are 2 kinds of engraving on minerals, depending on the composition: Laser etching mainly for slates, tiles and bricks. Such materials react with white colour when lazed, which gives a naturally contrasted result. Deep laser engraving: marble, granite, basalt, lava stone, natural stone, pebbles, ceramic, porcelain and black granite It gives a non-contrasted or slightly contrasted result. Often, paint or lacquer is added in the engraving after to get a nice coloured result. Cutting minerals is not possible with a laser.

Engraving Granite or Marble with a text and a sometimes a photo is an ancient Funeral tradition (mainly in Europe and South America countries). Now, engraving on different kinds of stone is very popular in new markets like Jewelry, interior design and crafts, events, gifts and signage.

Laser Engraving

Laser engraving on minerals produces a result similar to sandblasting: a surface engraving that gives the impression that the stone has been bleached.

If the contrast is not sufficient for your customer or if you want a specific colour, Gravotech offers the popular “Gravolaque” lacquer range: yellow, green, blue, red, white, black, silver, gold and shiny gold are available as standard however your specific colour can also be developed on demand. Gravolaque is suitable for indoor and outdoor applications.

Photo engraved on mineral

Engraving photo on minerals can be complex as it depends on the surface state. Generally, the rule of a thumb is to set 300 DPI maximum on the photo resolution to obtain a good result. This resolution can be increased if the surface state is homogeneous and smooth. We recommend to use very dark black marble (or very light white marble) so the contrast is even more beautiful.

Gravolaque will always be necessary as marble does not contract naturally when engraved with a laser. 1.5’’ lens is recommended for photo engraving with a thin spot beam.

Minerals are not flammable, therefore stone laser engraving machine has a very limited risk of fire ignition, contrary to Acrylic or Wood processing when they need to be constantly watched.

    Mechanical machines can process minerals (engrave only), but we recommend it only for expert users, as bur diamonds are required and they can be very expensive. Moreover, the risk of cutter break increases as the granite quality decreases. Granite is popularly used for headstones and other memorials but images of loved ones or logos can only be engraved on granite using laser equipment.
