Choosing a Metal Nameplate

Aug 28 2015

The construction of a metal nameplate can vary depending on the application. A metal nameplate can be built to withstand both indoor and outdoor use, vary in thickness, and have different metal characteristics. Information on metal nameplates can also be printed using different processes. It is important to understand these factors when choosing a metal nameplate that is right for your application. The most popular metal nameplates are: aluminum, stainless steel, zinc, and brass. Each metal has characteristics that make it right for some applications, and less suitable for others. To help you understand which material is most appropriate for your application, we’ve listed key features and benefits of each material.

The Metals

Aluminum

  • Very good chemical and solvent resistance
  • Good water, abrasion, and oxidation resistance when lacquered or anodized
  • Most versatile nameplate for decorative applications

Stainless Steel

  • Excellent water, chemical, abrasion, and corrosion resistance
  • Ideal for harsh indoor or outdoor applications
  • Retains sheen

Zinc

  • High heat resistance
  • Zinc nameplates can be tinted and deep etched
  • Allows for high-end graphics with intricate detail

Brass

  • Resist tarnish from water
  • Very good chemical and abrasion resistance and good oxidation and corrosion resistance
  • Available in a glossy or matte finish when a decorative metal nameplate is desired

 

Print and Decorative Processes

In addition to choosing a material, there are several metal nameplate printing and processing options. Each process is slightly different, and the printing and manufacturing may change based on the application needs.

Screen Printing

In the screen printing process, a squeegee is used to force ink through a selectively masked fabric screen that is used as a stencil. Screen printing on metal nameplates provides vivid color and offers good ink durability.

Offset Lithographic and Flexographic Printing

Offset lithographic printing is a process where ink on a metal roller is applied to a cylindrical rubber stamp then transferred to a sheet of metal nameplates. It uses a four-color printing process that creates sharp images. Flexographic printing is similar to offset lithographic printing, however it allows the image to be transferred directly from a rubber roller to the nameplate. Flexographic printing has higher setup costs, but is more cost effective for large production runs.

Embossing

Embossing a metal nameplate raises the text or design above the original (normal) surface creating a three dimensional look.

Laser Marking

Laser marking uses amplified light to remove material from the surface of a metal nameplate. It is frequently used for barcoding and serialization.

Chemical Etching

Chemical etching is a process where chemicals are used to remove material from a metal sheet to create a message or design. The etched area can be filled with color to provide a more visually appealing nameplate. The process of adding color to an etched nameplate is known as etch and fill. Chemically etched nameplates will remain legible even if the surface is painted over or left untreated. Etched metal nameplates are also resistant to abrasion.

Photosensitive Processing

The photosensitive process is used to produce anodized aluminum nameplates. It creates a hard anodized layer that is infused with a silver compound which, when exposed to light, creates an activated latent image. This makes the nameplate more durable and corrosion resistant. Known for their extreme printing accuracy and quick turnaround times, anodized photosensitive processed nameplates are commonly used in military and automotive applications.

Stamping

Stamping is the opposite of embossing. It is used to depress copy below the surface of the metal nameplate. Stamping is often used for applying variable information onto nameplates.
