Chemical etching, a process that dates back to the Middle Ages, allows us to transfer the most complex artwork to a brass, bronze, copper or stainless steel surface. When used in combination with Gemini’s cast and precision tooled plaques, our etched medallions and emblems provide the precision needed to accentuate any plaque or marker.
Premium etched plaques in aluminum, bronze, brass, copper or stainless steel and can be produced as thin as 1/16" thick. Laser engraved anodized aluminum or polished granite.
Etched photos are created with halftone images to provide a permanent, exterior-grade solution.
We have a stringent in-house laboratory testing process for all metals and paints. Our finishes have withstood thousands of hours’ exposure to salt fog, moisture, heat cycles, and UV light so we can confidently say they’ll last a lifetime.
For the ultimate in permanence, Gemini can engrave your artwork or copy onto polished black granite, which is suitable for interior or exterior applications. Choose from 11 common shapes and sizes up to 18” x 24”. For larger projects, use the six rectangle or square sizes in tandem to create your desired size.
The standard on all Gemini etched plaques is recessed text and graphics that are paint-filled.
Raised text or graphics means the background will be painted, leaving the text or graphics in the alloy color. (There are stroke and artwork limitations with raised graphics.)
A sketch or drawing can be etched with fabulous results by reproducing a black and white line drawing. Since no halftone screen is used in the process, the fine lines are expertly captured in exquisite detail. Designed for indoor applications and suitable for some outdoor applications.
Etched photos are created with halftone images, which resemble newspaper photographs and have visible dot patterns. The dots are filled with black ink to contrast with the brushed metal finish. High contrast photographs work best for etched images.
The Metal Image process offers greater detail than chemical etching. The porcelainized stainless steel is impervious to nearly all conditions, and the process is less expensive than etching, with a faster turnaround time. Alloy C304 / Optional Alloy 316. Only black copy or design is available.
Gemini guarantees all its exterior products for life.

Etched plaques maintenance guide.
All etched plaques 1/4" thick and thicker are drilled and tapped.
Plaques thinner than 1/4" can be stud mounted with welded stud bosses.
Strips of very high bond tape are applied to the back of the plaque.
Holes are drilled through the surface of the plaque. Specify screw size and if the holes should be countersunk. (Plaques 1/16” thick cannot be countersunk and will include round head screws.)
Stud Mounted letters are installed with Mounting Patterns.
