COMMENTS
There is a process called Laser Color Marking which enables the color filling of anodized
aluminum. First, coat or spray the aluminum with a clear acrylic finish. After the finish has
thoroughly dried, laser engrave the graphic onto the aluminum. Then take a water based
marker, such as those found in an art supply store, and swab on the ink into the engraved area.
You can actually see the ink get absorbed into the engraved area but not the unengraved area.
The ink will appear lighter in color because the white engraved area tends to lighten the shade.
Use a darker tint marker to compensate for the lighter effect. Wipe off the excess with a soft, lint
free cloth. Finish the piece by applying another coat of clear acrylic finish and let dry.
DO NOT ATTEMPT TO ENGRAVE DEEPLY OR CUT THIS MATERIAL
WITH THE LASER SYSTEM. High Power and low Speed settings can cause
the laser beam to reflect off of this material which can damage the laser system
and can be a safety hazard. Damage caused by this type of abuse WILL NOT
be covered under warranty.
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.
