COMMENTS
Most marble and polished stones will turn white when engraved. Masking is not necessary and
light engraving works out better than heavy and deep engraving. Engraving deeply will cause a
highly detailed image to appear washed out. The objective is to engrave deep enough to turn the
marble white and provide a good contrast. Too much power can also cause the material to
discolor and turn brown as if it were burned. Photographs look great when engraved on marble,
especially darker marbles where the whiteness of the engraving really stands out. Avoid using
marble that is very textured looking. The texture washes out the details of the engraving. Try to
use uniformly colored marble and related stones. Marble can also be paint filled by using a wax
based paint. Rub the paint on with a fingertip, let dry and then buff with a soft cloth. The paint
will only adhere to the engraved surface and not the surrounding areas.
ENGRAVING THIS MATERIAL PRODUCES ABRASIVE PARTICLES. Clean
the laser system more frequently to reduce wear and tear on the motion system
components and optics. Damage to the laser system from inadequate or
insufficient maintenance WILL NOT be covered under warranty.
