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.

WARNING: 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.
