Laser Etching Process:
What is laser etching? The laser Etcher transfers
an image from the computer into material of all kinds such as stone,
glass, mirror, wood, certain plastics, and so on.
How is this image embedded into the surface? With
industry BLACK GRANITE, the laser actually super-melts the surface of
the stone, forming on oval trench that has been measured with a scientific
microprobe to be 14 microns deep. The laser throws up a ridge above
the trench that is another 14 microns high. This makes a total etching
that is 28 microns deep! The repeated small ovals of trenches make
up the matrix of the photographic image. For every time the laser fires,
a trench is dug into the surface and through the polish of the stone.
This polish can not be replaced. The material that was thrown up around
the trench cools and can not be noticed beyond a very slight texture
- yet it adds to the etched surface depth.
Marble doesn't super-melt in the same manner as
granite, but is 'eroded' away by the laser as fine marble dust. The
polished surface is also broken, as it is in granite, and can not be
replaced. Marble can scratch over time and is recommended for home usage,
wall murals, and accent pieces. Marble produces an incredibly detailed
rendering of the photograph.
All stone is a natural product that contains
irregularities, fissures, various particle sizes - no stone is exactly
the same as another! This adds to the character of customized stone
