Laser etching granite process.
The result is both photo realistic and highly detailed.
While laser engraving removes as much as two one hundredths of an inch of material from the surface of the material to create a discernible cavity laser etching melts just the first thousandth.
There are a few reasons for this.
Laser engraving on stone is particularly effective with dark polished natural stones like granite marble and basalt.
Laser etching involves manipulating an image photograph or other and having that image engraved directly onto black granite with a laser machine.
Applications for stone engraving.
The etching or engraving process consists of processing a photograph either digital or print that has been scanned through a series of photographic editing computer programs and turning it into a high contrast black and white picture.
Laser etching is a process where a high heat laser beam is used to melt the surface of the target material the melted material expands and causes a slightly raised mark that reveals the desired image.
Laser engraving technology is the most advanced method for personalizing stone items.

Laser etching is more than twice as fast as engraving and annealing making it the fastest laser marking process.
Though all colors can be laser etched for these materials the choices and are better for granite.
It is important to note that the quality of the etched image greatly depends on the quality of the image we receive.
The darker colors are better for laser etching with dark black granite being the best.
The surface of the stone is melted during laser engraving so the material is processed directly.
To increase the etching speed you can use systems with higher laser powers.
Laser engraving as it applies to etching on stone is a process of removing the polished surface with a co2 laser and permanently etching into the natural exposed material depending on the images parameters.
The customized laser etching process begins when we receive your favorite picture.
The process is much more efficient because there is no need to create a template and the laser beam is the universal tool for all shapes and material thicknesses.
Granite the world s third strongest material has a matchless beauty and when paired with our laser etching technology a simple photo is transformed into a work of art.
For most marking applications the maximum laser power you will need is 100w.
The picture is then sent to the laser where it is engraved into granite using a laser beam 3 thousands of an.
