Historically signage was made with durable natural materials such as wood, metal and stone.  However, this changed in the 1950s with increased fossil fuel production and the advent of inexpensive plastic sheet goods. In recent decades plastics have become the default standard material for signage, and in 2024 it is hard to find a business sign that is not made of plastic.

However, sign industry dynamics are shifting.  Fossil fuel and plastics costs increasing, and we are more aware of their negative climate impacts. Additionally, new wood production and software technology increase the benefits of and options for custom wooden architectural signage.


Green Dot Sign® developed patent pending 3D printing technology for ADA sign applications. Combining this innovation with our wood manufacturing and commercial sign expertise means that beautiful, world class sustainable signage are now an option for all buildings and brands.

Almost all our use wood or metal as their primary material, and use a combination of the below manufacturing methods.  Methods can be combined to provide an amazing variety of signage in bright colors, natural textures and everything in between.

CNC routing and cutting – Reductive manufacturing method that cuts letters, logos and design elements.  Uses a spinning bit, so inner corners will have a radius.

Laser etching and cutting – Burns images, logos and letters into a wood surface.  High resolution, so can be used for photographs as well as vector content.  Laser cut elements have a carbonized black edge.

Flat digital printing – White plus CMYK printing direct to metal or wood.  For bright colors or traditional looking sign faces, letters and logos print a white undercoat followed by CMYK.  Many CMYK colors direct wood create a transparent, colorful and attractive appearance.

ADA tactile character 3D printing – Raised letters with a screened CMYK top, and braille may be clear of in color.  Note ADA contrast requirements when deciding background and letter color.

ADA metal characters on wooden background – Machined aluminum, bronze or brass letters adhered to wood, generally in conjunction with clear braille.

Inlays – metal, commercial laminates, wood strips or veneers, as well as material with brand, historical or emotional value can be easily inlaid into sign bases.

Wood Dyeing – We offer any color using this set of dyes. Not all wood species deliver vibrant results, so please start with your desired color and contact us.  Signs are sealed after dyeing with bio-based or blended bio-based oil options.


Through ADA signage specifications and product selection, the AECO community wields tremendous influence. There are over 500 million pounds of fossil fuel derived, non-biodegradable plastic in use as ADA signs right now.  That’s just ADA signs, and an estimate that does not include government buildings. 

Someone designed these signs and chose their material.  And, someone can make a difference going forward. When drafting ADA signage specifications for your brand standards, firm or your next project, please consider the following:

PVC and vinyl free – In the sign world, PVC is a plastic sheet material and vinyl is a thin film with adhesive to be printed or cut, then applied to a substrate, wall or window.  These are the same chemical, and amongst of the worst of the mass-produced plastics.  As a matter of fact, they are on the Red List and we encourage consumers to not buy PVC products, and designers to consider better alternatives.  

Phthalate free – Phthalates are a group of harmful chemicals added to plastics to increase flexibility.  As a society we’ve removed them from our canned foods because they mess with hormones, so why ask anyone to breathe them in?  By requiring phthalate free signs, factory workers, signage installers and office tenants all get a better work environment.  

Bio based materials – Specify a minimum of 75% bio-based materials in your sign packages.  

Made in the U.S. – Domestic production ensures a minimum level of labor and environmental standards from your direct signage vendor as well as any significant Tier 1 and Tier 2 suppliers.

Green Dot Sign® adheres to all of the above environmental sustainability criteria.  Of course we want a chance to earn your business, and of course you want to insure a competitive set of specifications that get a fair price.  But that doesn’t mean you should be afraid to include these requirements because ADA sign vendors who can meet them are hard to find.  Just the opposite, any sign company can do what we do. And,  if you ACTUALLY just read this, you’re the person to help make sure there are more.
