From Digital Artwork to Physical Signs

Converting Artwork Into CAD Files

Before a sign can be fabricated, digital artwork must be converted into CAD (Computer-Aided Design) files.

CAD files translate design artwork into instructions machines can follow. These instructions define tool paths, cutting depths, and the sequence of operations required to produce the sign.

Vector artwork alone does not contain all the information required for fabrication. It defines shapes visually but does not define how those shapes will be physically produced.

To fabricate a sign correctly, the design must be translated into precise machine instructions that account for tooling, spacing, and material behavior.

Why Artwork Is Retyped

A step that often surprises designers is that sign manufacturers frequently retype the artwork text instead of directly using the supplied vector files.

This is not done to change the design, but to ensure accuracy and ADA compliance during fabrication.

At tactile scale, small issues in digital artwork can become significant problems. Font distortion, incorrect spacing, or inconsistent kerning can affect both readability and braille placement.

Retyping text allows manufacturers to correct these issues and ensure the sign meets both visual and tactile standards required for ADA signage.

Retyping helps achieve several important goals:

• preventing font distortion at tactile sizes
• correcting kerning that could affect compliance
• ensuring proper spacing between characters
• enabling accurate braille placement
• guaranteeing that tactile text and braille correspond exactly
• ensuring proper tactile character sizing for ADA compliance
• producing accurate text-to-braille translation

In this sense, retyping functions as a form of quality control within the manufacturing process.

Using Customer-Supplied Artwork

In some cases, customers request that their artwork be used exactly as provided, without modification to the text or typography.

When this occurs, the artwork can typically be reproduced as supplied. However, it is important to understand that when customer typography is used directly, the manufacturer may not be able to verify whether the chosen font meets ADA tactile character requirements.

While we can verify that the braille translation and placement are compliant, the compliance of the supplied font itself cannot always be confirmed if the text is not rebuilt within the manufacturing workflow.

For this reason, when customer artwork must be used exactly as provided, the text is typically produced using UV printing rather than routed or engraved tactile characters.

UV printing allows the artwork to be reproduced accurately while avoiding potential tool-pathing issues that can occur when engraving complex or non-optimized vector text.

This approach ensures that the customer’s artwork is reproduced faithfully while maintaining reliable braille production and avoiding fabrication issues during machining.

Why Physical ADA Signs Differ from Digital Designs

ADA-compliant signs produced via CNC routing or engraving will never perfectly match what appears on screen.

Understanding why helps designers, architects, and clients set realistic expectations.

In digital design environments, artwork is created using idealized vector shapes displayed on a perfectly lit monitor. Manufacturing, however, must deal with real tools, real materials, and the physical limitations of machining.

Small variations that appear in finished signage are not defects; they are normal results of the fabrication process.

Digital Design vs Physical Manufacturing

In digital design, letters and graphics are defined by vector paths that have zero thickness. These shapes can be infinitely scaled and remain mathematically perfect.

Physical manufacturing operates very differently.

Signs must be cut using tools that have real dimensions. CNC routers use cutting bits with specific diameters, and even laser cutters produce a cut with measurable width.

Because of this, machines cannot follow vector lines exactly as they appear in digital artwork.

Every fabrication method introduces small variations because the design must be interpreted through tools and materials.

Even extremely precise manufacturing processes cannot reproduce a digital design with perfect mathematical accuracy. Instead, they operate within tolerances that define acceptable variation.
