Glossary
Architectural Plaques
Plaques produced using a high-speed machining process on sheets of metal in varying thicknesses.
Cast Plaques
Cast plaques are made using a traditional sand casting process that uses molten metal without any pressure. Gemini’s cast plaques offer greater depth and dimension than architectural plaques.
Color
The color of a letter is created using a pigmented plastic or paint. Gemini has many standard pigments and paints and also matches color upon request.
Depth
The measurement from the face of the letter to the back.
Dimension
The overall height and width of a letter. This is useful to know when
establishing the length of a given set of letters.
Dimensional Letters
Letters, logos or symbols, either cut out, cast, molded or fabricated in a material such as metal or plastic to create a raised condition.
Display Letters
Letters specifically designed for interior use.
End User/Consumer
The person or business that ultimately purchases the sign. This includes hospitals, governments, convenience stores and retail shops.
Etched Plaques
Plaques produced using a process in which letters and images are applied to the surface using chemical corrosion.
Fabricated Letters
Custom dimensional metal letters constructed using a thin metal that has been cut, shaped and soldered on the inside to produce a deep, hollow product.
Finish
The final surface treatment of the face of a letter. For example, metal letters are available in finishes including brushed, buffed, anodized or painted.
Flat Cut Letters
Acrylic letters that are cut from sheets of acrylic using a laser.
Font
The individual typestyle of a letter. Times, Helvetica and Futura are all standard fonts available from Gemini.
Illuminated Letters
Letters that have a light source that illuminates them. Neon and LED (light-emitting diodes) are the most common lighting methods.
Injection Molded
Precision-made tools are loaded into an injection-molding hydraulic press. Granular plastic is heated and forced through a hat cylinder, then injected into the closed mold.
Laser Cut Metal Letters
Letters that are cut out of a sheet of metal using a laser, per custom art supplied or using Gemini’s standard letter fonts.
Material
The material used to make the letter or logo. Gemini cuts letters from sheets of acrylic, bronze, aluminum, brass, etc.
Minnesota Letters
Gemini’s line of injection molded letters.
Mounting Method
Any of various methods used to install a plaque or a set of letters to a surface. Different methods are used depending on the size, thickness and weight of the letters, and the type of installation surface.
Product Family
Product families are grouped by material. Gemini product families include plastic, metal, illuminated, display, plaques and sign components.
Sign Professional
Someone who works in the signage, graphics, recognition or award industries.
Size
The height of a letter. In a specific typestyle, lowercase letters are slightly smaller than uppercase letters.
Style
The design used in lettering to make character sets or signs.
Vacuum-formed Letters
Sheets of plastic are heated until malleable enough to be draped over molds on a vacuum table. Suction is then applied until the sheet of plastic has taken the contour of the mold placed beneath it. Letters are then cut from the sheets.
Water Jet Cut Metal Letters
Letters that are cut out of a sheet of metal, per custom art supplied or using Gemini’s standard letter fonts. The water jet cuts metal with a 50,000 PSI stream of water that carries garnet, an abrasive mineral that actually does the cutting as it shoots through the small nozzle on the machine.
