Beautiful Signs for a Better Planet

Signage Specifications


Green Dot Sign® develops processes and technologies dramatically reducing plastic use in signage.  We hope the signage specifications below help make your design efforts smooth and easy. They are best used in conjunction with the design guide and are oriented to custom signage.

Did you know almost all sign plastic is fossil fuel derived, not biodegradable and almost never recyclable?

This means traditional signs may look great for a while, but they’ve got an ugly past and an ugly future.  So how good do they look when you see the whole picture?

Overview: Wooden Architectural Signage

Prior to the mid 1900’s, signage was made with materials such as wood, metal and stone.  With the advent of inexpensive plastic sheet goods due to wildly increased fossil fuel production, this all changed from the 1950’s onward.  Now, you’d be hard pressed to find a modern business sign that doesn’t use plastic.

However, new production and software technology for CNC routing, laser etching and 3D printing, as well as the increased cost of plastics and fossil fuel have changed this equation.

In fact, Green Dot Sign® developed patent pending 3D printing technology for ADA sign applications since this is the most difficult aspect of sustainable architectural signage.  Combining this new option with our wood manufacturing and commercial sign expertise means beautiful, world class sustainable signage is now an option for all buildings and brands.

Overview: Manufacturing Methods

Almost all Green Dot Signs use wood or metal as the primary material for the following manufacturing methods.  Combine them offer an amazing variety of signage in bright colors, natural textures and everything in between.  Brief descriptions are included to assist with your efforts.

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.

Exterior ADA signage, machined solid metal plate:  For exterior tactile signage with braille, machining from solid metal insures long life with no layers to delaminate or adhesive to fail.

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.

Painting: Pantone, BM or SW paint matching for either wood or metal.

Sealing: Prevents discoloration, protects wood and highlights natural grain at the same time.  We offer several standard sealing options detailed on the design page.  For most cases select blended bio-based oil.  Note our standard sealers are easy to touch up for MRO, do not crack or peal and do not create water rings or marks.

Green Dot Sign® makes sustainable signs an easy part of your building project.  Eco-friendly ADA signage strengthens your brand and provides design, cost and environmental advantages.

Via patent-pending, low-waste manufacturing processes we 3D print raised ADA compliant sign content directly to responsibly sourced wood and other natural materials.  We never use vinyl, plastic sheet of any type, toxic inks or unnecessary adhesives to make signs.  By not using machined plastics, every one of our signs keeps 250 grams of plastic from being tossed into a landfill.

FSC Sustainable Signs

Extended Producer Responsibility Icon


Forest Stewardship Council (FSC) 100% certified wood is used for all quick ship standard ADA signs and most custom wood signage. FSC promotes environmentally sound, socially beneficial and economically prosperous forest management. Our FSC Certificate is C019842.


Aspen Base ADA Signage is covered by a Red List Approved Declare label.  Declare is a transparency platform managed by the International Living Future Institute (ILFI) requiring building product constituent disclosure to 100 PPM. Our Declare ID is GDS-0001.


Durable Green Dot signs last a long time, however, almost every facility is eventually remodeled.  At the end of lifecycle, all our eco-friendly signs are eligible to be recycled through our Extended Producer Responsibility Program.

Upon receipt of used ADA signs, raised braille, lettering and pictograms are planed off the sign base. The wood sign base is shredded then recycled as animal bedding, and afterwards applied as fertilizer at a local farm.


As permanently installed products, Green Dot Aspen Base ADA Signs can contribute to USGBC LEED® building certification credits in three ways. Under LEED® v4 and v4.1 our signage fits into the Materials and Resources category and Building Product Disclosure and Optimization Sourcing of Raw Materials and Material Ingredients LEED credits. FSC Aspen Base Signs can also contribute to ILFI Living Building Challenge projects under the Materials petal.

Through signage specifications and product selection, the AECO community wields tremendous influence. We estimate there are over 500,000,000 pounds of fossil fuel derived, non-biodegradable plastic is in use as ADA signs right now.  That’s JUST ADA signs, and a conservative estimate that does not include government buildings.  The main plastics in use are acrylic and PVC. 

Some one designed them.  Some one chose their material.  And some one can make a difference going forward, too.  

When drafting signage specifications for your brand standards, architectural firm or even just 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 consider not buying 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, such as a Green Dot Sign®, factory workers, installers and folks sitting in offices all get a better work environment.  

Bio based sign 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 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 vendors who can meet them are hard to find.  Just the opposite – we aren’t special, any sign company can do what we do, and you’re the person to help make sure there are more like us.
