residue to form just like with non-mirrored acrylic. A double image will appear if engraving on the front
side of the mirror. It is not necessary to mask the backside when engraving because the mirrored
backing shields the acrylic from smoke damage. To cut mirrored acrylic, it might be necessary to
remove all original masking, re-mask with transfer tape, and dampen the tape with water from a spray
bottle. Next, place the acrylic in the laser with the mirrored surface facing upwards and elevate at least
1/8 inch above the table. The laser beam will not reflect off of the mirrored surface because it is
absorbed by the acrylic first. Sometimes cutting the acrylic from the back side will cause the mirrored
backing to distort and crack from the intense heat required to cut. If the combination of engraving and
cutting is desired, our suggestion is to engrave the backing, unmasked, remove the acrylic, mask both
sides with transfer tape, flip the acrylic over, dampen, elevate, re-focus, and cut from the front side.
When paint filling the engraved area, make sure to use an acrylic based paint or paint that does not
contain acetone or alcohol as these chemicals will crack the acrylic. Water based paints also work very
well. Since the mirrored backing serves as a masking, it is not necessary to mask the back side before
engraving.
